Bribery Act in force The Bribery Act 2010 came in to force last Friday, 1 July 2011. Much has been written about its likely implications. At the start of the debate, it would even be fair to say there was a degree of scare-mongering by some in ter...

In our computational study, we use molecular simulations to substantiate a hypothetical mechanism for glycosidic bond cleavage in the presence of a single catalytic acid at the active site of the mutant D10N HiCel45A. In addition to discussing this plausible mechanism from the context of structurally related MltA lytic transglycosylase and subfamily C GH45s, we also suggest the implications of the plausible mechanism for our current understanding of the action of expansins and lytic transglycosylases. As correctly pointed out by Professor Cosgrove (1), there is large body of evidence, a significant portion of which was regrettably not discussed in our paper, that suggests that expansins are incapable of lytic action on polysaccharide substrates. Whereas these insights do not change the results or the conclusions of our article, we would like to thank Professor Cosgrove for these additional insights. In particular, our main point with respect to expansins is that our results suggest the possibility that expansins are capable of nonhydrolytic lytic activity. Our intention was not to suggest this was the mechanism of expansins, but that it should be considered based on our results and the similarity of the active sites.The molecular mechanisms of how expansins enable cell wall expansion remains to be fully understood. Whereas our proposed mechanism resulting in the formation of the 1,6-anhdro product might be found in expansins and might contribute to the mode of action of expansins, we would like to emphasize that the intent of this study was only to suggest this as a...

From their simulations of endoglucanase Cel45A, Bharadwaj et al. (1) propose that structurally related expansins and MltA may cut glycan backbones without generating reducing ends. This is tenable for MltA, a peptidoglycan lytic transglycosylase whose action produces nonreducing 1,6-anhydro products, but is untenable for expansins.Expansins loosen plant cell walls and induce wall expansion. Contrary to the assertion by Bharadwaj et al., the conclusion that expansins are not lytic is not merely based on lack of new reducing ends but is supported by multiple (negative) tests for polysaccharide cleavage that do not rely on detection of reducing ends. At least eight studies with three divergent groups of expansins document this point. For instance, α-expansin did not reduce the viscosity of various wall polysaccharide solutions, an endolytic assay that does not rely on measuring reducing ends (e.g. see Ref. 2 and other studies).Walls treated with α-expansin did not release saccharide fragments, measured by pulsed amperometric detection, which can detect nonreducing saccharides (3).In the case of β-expansins, protein treatments did not cleave the backbones of a wide range of dye-coupled cross-linked wall polysaccharides; nor did they cleave backbones of polysaccharides extracted from plant cell walls, measured by gel permeation chromatography (4).For five microbial expansins, tests with a range of dye-coupled cross-linked polysaccharides likewise did not detect lytic activity (e.g. see Ref. 5). Thus, extensive published evidence argues against lytic action by expansins, as proposed by Bharadwaj (1), and attempts to identify 1,6-anhydro products seem unlikely to succeed.

‘I take comfort in the knowledge that, even though you are not here, your work continues to make children happy’

I was so worried about handing my little boy over during his first week of school, but you made it easier. You smiled at him like a mother would at her own child. You radiated warmth and your hugs were always on offer.

After a day in class with you, C would come home singing. Whenever I hear Do Your Ears Hang Low or see him stretching to the sky when singing about the days of the week, I will think of you. I didn’t tell you at the time, but I loved your morning song so much that I implemented it in my own class (I’m a teacher too). The first time we sang it after losing you was hard but, as time passes, I take comfort in the knowledge that, even though you are not here, your work continues to make children happy.

Jill Wallis says she has never had so much contact with family and friends as she has had since the lockdown began

You have published many articles about the challenges of isolation, most recently your long read (Patterns of pain: what Covid-19 can teach us about how to be human, 7 May). But there is one interesting outcome you may not have considered.

Many of those of us who always live alone are finding we are much more in contact with loved ones than previously. I’ve lived alone since being widowed 16 years ago, and I’ve never had as much contact with my family and even my friends than I’ve had since the lockdown began.
