Crystallographic and kinetic analyses of the FdsBG subcomplex of the cytosolic formate dehydrogenase FdsABG from Cupriavidus necator [Molecular Biophysics]

Formate oxidation to carbon dioxide is a key reaction in one-carbon compound metabolism, and its reverse reaction represents the first step in carbon assimilation in the acetogenic and methanogenic branches of many anaerobic organisms. The molybdenum-containing dehydrogenase FdsABG is a soluble NAD+-dependent formate dehydrogenase and a member of the NADH dehydrogenase superfamily. Here, we present the first structure of the FdsBG subcomplex of the cytosolic FdsABG formate dehydrogenase from the hydrogen-oxidizing bacterium Cupriavidus necator H16 both with and without bound NADH. The structures revealed that the two iron-sulfur clusters, Fe4S4 in FdsB and Fe2S2 in FdsG, are closer to the FMN than they are in other NADH dehydrogenases. Rapid kinetic studies and EPR measurements of rapid freeze-quenched samples of the NADH reduction of FdsBG identified a neutral flavin semiquinone, FMNH•, not previously observed to participate in NADH-mediated reduction of the FdsABG holoenzyme. We found that this semiquinone forms through the transfer of one electron from the fully reduced FMNH−, initially formed via NADH-mediated reduction, to the Fe2S2 cluster. This Fe2S2 cluster is not part of the on-path chain of iron-sulfur clusters connecting the FMN of FdsB with the active-site molybdenum center of FdsA. According to the NADH-bound structure, the nicotinamide ring stacks onto the re-face of the FMN. However, NADH binding significantly reduced the electron density for the isoalloxazine ring of FMN and induced a conformational change in residues of the FMN-binding pocket that display peptide-bond flipping upon NAD+ binding in proper NADH dehydrogenases.

Webinar: OPEC, Falling Oil Prices and COVID-19

Corporate Members Event Webinar

7 April 2020 - 1:00pm to 2:00pm

Online

Event participants

Julian Lee, Oil Strategist, Bloomberg LP London
Dr John Sfakianakis, Associate Fellow, Middle East and North Africa Programme, Chatham House; Chief Economist and Head of Research, Gulf Research Center
Professor Paul Stevens, Distinguished Fellow, Energy, Environment and Resources Programme, Chatham House
Emily Stromquist, Director, Castlereagh Associates
Chair: Dr Sanam Vakil, Deputy Director and Senior Research Fellow, Middle East and North Africa Programme, Chatham House

In early March, global oil prices fell sharply, hitting lows of under $30 a barrel. Two factors explain this collapse: firstly the decrease in global demand for oil as a result of the COVID-19 pandemic and, secondly, the breakdown in OPEC-Russian relations and the subsequent Saudi-Russian price war which has seen both countries move to flood the market with cheap oil.
 
Against this backdrop, the panellists will reflect on the challenges currently facing OPEC as well as the oil industry as a whole. How are OPEC countries affected by the ever-evolving Covid-19 pandemic? What are the underlying causes behind the Saudi-Russian price war? Is the conflict likely to be resolved soon? And what are the implications of these challenges for the oil industry?

This event is part of a fortnightly series of 'Business in Focus' webinars reflecting on the impact of COVID-19 on areas of particular professional interest for our corporate members and giving circles.

Closing the Global Access Gap in Palliative Care and Pain Relief: A Top Priority in Achieving Universal Health Coverage

Invitation Only Research Event

17 July 2019 - 12:30pm to 5:00pm

Chatham House | 10 St James's Square | London | SW1Y 4LE

Event participants

Dr Tedros Adhanom Ghebreyesus, Director-General, World Health Organization 

The Lancet Commission on Palliative Care and Pain Relief estimated that in 2015, 61 million people experienced serious health-related suffering (SHS) that could have been ameliorated by palliative care. A large proportion of this burden – more than 80 per cent – fell on low- and middle-income countries (LMICs) despite an essential package of palliative care and pain relief services being cost-effective and affordable. As the director general of the World Health Organization (WHO) argues, there cannot be UHC without palliative care and thus, closing this coverage gap should be a top priority for the global UHC movement.

The Centre on Global Health Security at Chatham House, building on the momentum of the Lancet Commission, is hosting a roundtable focused on the global unmet need for palliative care and effective pain relief. The primary purpose of this roundtable is to convene leading experts, palliative care service users and advocates with key figures from the UHC movement and global health to highlight the importance of prioritizing this vital part of the continuum of care in UHC reform processes. The roundtable will serve as a scholarly discourse in translating the recommendations of the Lancet Commission into concrete actions, focusing on the political and economic dimensions.

Coronavirus Vaccine: Available For All, or When it's Your Turn?

4 May 2020

Professor David Salisbury CB

Associate Fellow, Global Health Programme
Despite high-level commitments and pledges to cooperate to ensure equitable global access to a coronavirus vaccine, prospects for fair distribution are uncertain.

When the H1N1 influenza pandemic struck in 2009, some industrialized countries were well prepared. Many countries’ preparedness plans had focused on preparing for an influenza pandemic and based on earlier alerts over the H5N1 ‘bird flu’ virus, countries had made advanced purchase or ‘sleeping’ contracts for vaccine supplies that could be activated as soon as a pandemic was declared. Countries without contracts scrambled to get supplies after those that already had contracts received their vaccine.

Following the 2009 pandemic, the European Union (EU) developed plans for joint-purchase vaccine contracts that any member state could join, guaranteeing the same price per dose for everyone. In 2009, low-income countries were unable to get the vaccine until manufacturers agreed to let 10 per cent of their production go to the World Health Organization (WHO).

The situation for COVID-19 could be even worse. No country had a sleeping contract in place for a COVID-19 vaccine since nobody had anticipated that the next pandemic would be a coronavirus, not an influenza virus. With around 80 candidate vaccines reported to be in development, choosing the right one will be like playing roulette.

These candidates will be whittled down as some will fail at an early stage of development and others will not get to scale-up for manufacturing. All of the world’s major vaccine pharmaceutical companies have said that they will divert resources to manufacture COVID-19 vaccines and, as long as they choose the right candidate for production, they have the expertise and the capacity to produce in huge quantities.

From roulette to a horse race

Our game now changes from roulette to a horse race, as the probability of winning is a matter of odds not a random chance. Countries are now able to try to make contracts alone or in purchasing consortia with other states, and with one of the major companies or with multiple companies. This would be like betting on one of the favourites.

For example, it has been reported that Oxford University has made an agreement with pharmaceutical company AstraZeneca, with a possibility of 100 million doses being available by the end of 2020. If the vaccine works and those doses materialize, and are all available for the UK, then the UK population requirements will be met in full, and the challenge becomes vaccinating everyone as quickly as possible.

Even if half of the doses were reserved for the UK, all those in high-risk or occupational groups could be vaccinated rapidly. However, as each major manufacturer accepts more contracts, the quantity that each country will get diminishes and the time to vaccinate the at-risk population gets longer.

At this point, it is not known how manufacturers will respond to requests for vaccine and how they will apportion supplies between different markets. You could bet on an outsider. You study the field and select a biotech that has potential with a good production development programme and a tie-in with a smaller-scale production facility.

If other countries do not try to get contracts, you will get your vaccine as fast as manufacturing can be scaled up; but because it is a small manufacturer, your supplies may take a long time. And outsiders do not often win races. You can of course, depending on your resources, cover several runners and try to make multiple contracts. However, you take on the risk that some will fail, and you may have compromised your eventual supply.

On April 24, the WHO co-hosted a meeting with the president of France, the president of the European Commission and the Bill & Melinda Gates Foundation. It brought together heads of state and industry leaders who committed to ‘work towards equitable global access based on an unprecedented level of partnership’. They agreed ‘to create a strong unified voice, to build on past experience and to be accountable to the world, to communities and to one another’ for vaccines, testing materials and treatments.

They did not, however, say how this will be achieved and the absence of the United States was notable. The EU and its partners are hosting an international pledging conference on May 4 that aims to raise €7.5 billion in initial funding to kick-start global cooperation on vaccines. Co-hosts will be France, Germany, Italy, the United Kingdom, Norway and Saudi Arabia and the priorities will be ‘Test, Treat and Prevent’, with the latter dedicated to vaccines.

Despite these expressions of altruism, every government will face the tension between wanting to protect their own populations as quickly as possible and knowing that this will disadvantage poorer countries, where health services are even less able to cope. It will not be a vote winner to offer a share in available vaccine to less-privileged countries.

The factories for the biggest vaccine manufacturers are in Europe, the US and India. Will European manufacturers be obliged by the EU to restrict sales first to European countries? Will the US invoke its Defense Production Act and block vaccine exports until there are stocks enough for every American? And will vaccine only be available in India for those who can afford it?

The lessons on vaccine availability from the 2009 influenza pandemic are clear: vaccine was not shared on anything like an equitable basis. It remains to be seen if we will do any better in 2020.

A novel GPER antagonist protects against the formation of estrogen-induced cholesterol gallstones in female mice [Research Articles]

Many clinical studies and epidemiological investigations have clearly demonstrated that women are twice as likely to develop cholesterol gallstones as men, and oral contraceptives and other estrogen therapies dramatically increase that risk. Further, animal studies have revealed that estrogen promotes cholesterol gallstone formation through the estrogen receptor (ER) α, but not ERβ, pathway. More importantly, some genetic and pathophysiological studies have found that G protein-coupled estrogen receptor (GPER) 1 is a new gallstone gene, Lith18, on chromosome 5 in mice and produces additional lithogenic actions, working independently of ERα, to markedly increase cholelithogenesis in female mice. Based on computational modeling of GPER, a novel series of GPER-selective antagonists were designed, synthesized, and subsequently assessed for their therapeutic effects via calcium mobilization, cAMP, and ERα and ERβ fluorescence polarization binding assays. From this series of compounds, one new compound, 2-cyclohexyl-4-isopropyl-N-(4-methoxybenzyl)aniline (CIMBA), exhibits superior antagonism and selectivity exclusively for GPER. Furthermore, CIMBA reduces the formation of 17β-estradiol-induced gallstones in a dose-dependent manner in ovariectomized mice fed a lithogenic diet for 8 weeks. At 32 μg/day/kg CIMBA, no gallstones are found, even in ovariectomized ERα (–/–) mice treated with 6 μg/day 17β-estradiol and fed the lithogenic diet for 8 weeks. In conclusion, CIMBA treatment protects against the formation of estrogen-induced cholesterol gallstones by inhibiting the GPER signaling pathway in female mice. CIMBA may thus be a new agent for effectively treating cholesterol gallstone disease in women.­

Secrecy, spies and the global South: intelligence studies beyond the 'Five Eyes' alliance

6 November 2019 , Volume 95, Number 6

Zakia Shiraz and Richard J. Aldrich

The study of secrecy and spies remain subjects dominated by Anglo-American experiences. In recent years there has been some effort to refocus the lens of research upon ‘intelligence elsewhere’, including the global South. This is partly because of intense interest in the Arab Spring and ‘managed democracy’, placing a wider range of secret services under the spotlight. However, the approach to research is still dominated by concepts and methods derived from studying the English-speaking states of the ‘Five Eyes’ alliance and their European outriders. This article calls for a re-examination of research strategies for Intelligence Studies and for those theorizing surveillance, suggesting that both fields have much to learn from area studies and development studies, especially in the realm of research practice and ethics. If the growing number of academics specializing in intelligence genuinely wish to move forward and examine the global South they will need to rethink their tool-kit and learn from other disciplines. We suggest there is a rich tradition to draw upon.

At face value, recent years have seen a deepening in Sino-Russian cooperation, from energy agreements, to the recent Huawei-MTS deal developing a 5G network in Russia. Ever larger-in-scale joint military exercises add to fears by some that the 'axis of convenience' is now a more genuine – and threatening – partnership.

This workshop will offer a sober assessment of the latest developments in Sino-Russian relations, shedding light on the underpinnings and practical realities of the relationship as well as on the long-term challenges of upholding cooperation.

The panel will discuss the different and potentially diverging interpretations of contemporary Sino-Russian relations as well as the implications for the rules-based international order.

This event is co-organized by the Chatham House Russia and Eurasia Programme and the University of Exeter and is supported by the British International Studies Association.

Attendance at this event is by invitation only.

The recalibration of Chinese assertiveness: China's responses to the Indo-Pacific challenge

8 January 2020 , Volume 96, Number 1

Feng Liu

In response to the changing geopolitical landscape in Asia, both China and the United States attempt to alter the regional order in their own favour, both in the economic and security realms. This article shows how diverging views on future arrangements are leading to strategic shifts and increasing tension between these two Great Powers. As part of its quest for Great-Power status, China has been actively pushing its regional initiatives such as the Belt and Road Initiative (BRI) and the Asian Infrastructure Investment Bank (AIIB), as well as adopting assertive security policies towards its neighbours. In contrast, in order to counter China's growing influence America's regional strategy is undergoing a subtle shift from ‘rebalancing to Asia’ to focusing on the ‘Indo-Pacific’ region. However, amid an intensifying trade war and other challenges facing the region, China has chosen to moderate its proactive foreign policy-orientation in the past few years. In particular, China has made attempts to downplay its domestic rhetoric, rebuild strategic relationship with India and Japan, and to reassure ASEAN states in the South China Sea. In response to the Indo-Pacific strategy, it would be more effective for China to articulate a more inclusive regional vision and promote an institutional framework that also accommodates a US presence in the region.

Webinar: Is It All Over For Globalization?

Research Event

15 April 2020 - 1:00pm to 2:00pm

Event participants

Will Hutton, Political Economist; Principal, Hertford College Oxford 
Chair: Champa Patel, Director, Asia-Pacific Programme, Chatham House

The coronavirus pandemic has led many to predict the end of globalization. Confronted with unprecedented social and economic challenges, countries are prioritizing their own citizens. Now, more than ever, international cooperation is necessary but, amidst the rise of nationalist-populist governments, global partnerships are absent or faltering. And as economies grind to a halt, so does international commerce — particularly in trade-dependent Asia, a region whose rise drove the period of 'hyper-globalization' which preceded the global financial crisis. 

Yet there are other possible futures too. The level of scientific collaboration and information-sharing now underway in search of a vaccine is unprecedented, and after a hesitant beginning the major powers have woken up to the importance of concerted economic stimuli. The virus may in some ways have the paradoxical result of bringing countries together, not driving them apart. Rather than causing its demise, it could help begin a new period in which globalization is not as deep, but at least is better managed and more equitable? Could this be the catalyst for a new coming together at home and abroad?

In this webinar, speakers debate what impact the COVID-19 pandemic will have on the future of globalization, both in Asia and around the world.

Pulling Out (from) All the Stops - Visiting all of NY's subway stops in record time

With 468 stops served by 26 lines, the New York subway system can make visitors feel lucky when they successfully negotiate one planned trip in a day. Yet these two New Yorkers, Chris Solarz and Matt Ferrisi, took on the task of breaking a world record by visiting every stop in the system in less than 24 hours. They used mathematics, especially graph theory, to narrow down the possible routes to a manageable number and subdivided the problem to find the best routes in smaller groups of stations. Then they paired their mathematical work with practice runs and crucial observations (the next-to-last car stops closest to the stairs) to shatter the world record by more than two hours!

Although Chris and Matt.s success may not have huge ramifications in other fields, their work does have a lot in common with how people do modern mathematics research

* They worked together, frequently using computers and often asking experts for advice;
* They devoted considerable time and effort to meet their goal; and
* They continually refined their algorithm until arriving at a solution that was nearly optimal.
Finally, they also experienced the same feeling that researchers do that despite all the hours and intense preparation, the project .felt more like fun than work.
