Oman, otherwise officially known as the Sultanate of Oman, is within the southeastern portion of the Arabian Peninsula. The country is surrounded by two sea bodies including the Arabian Sea in the southeast and the Sea of Oman in the northeastern portion. A larger body of water, the Indian Ocean, is also near Oman in the southeastern area like the Arabian Sea. Americans, Canadians, and other digital nomads from various countries can easily assimilate as digital nomads since English is a widely used language besides the official language, Arabic. While there is no digital nomad visa program in Oman, you can opt to apply for an employment visa. If you are a digital nomad, you will have to apply for various eVisas depending on where you are going, such as an eVisa Ethiopia. How To Apply for An Employment Visa in Oman Applying for an employment visa in Oman takes six steps with an overall turnaround time of up to 9 weeks long depending on individual processing time. The first step is the initiation process where you have to contact Fakhoury Global Immigration and send in the appropriate documents to start applying for the employment visa. This initial step only takes about 24-72 hours. The second step involves filling out the labor permit application and waiting for that to be approved within 3 to 4 weeks. For step 3, you must fill out the employment visa application and provide the mandated documents. Take everything to the closest Royal Oman Police location for full processing within 1 week to a month. The fourth step involves entering Oman where you can begin your digital nomad endeavors once this happens. For step 5, you need to have a health exam at one of the entity’s supported clinics. You will need a chest X-ray, blood tests to be sure you don’t have any bad diseases, as well as pee and poop samples for a full health profile. The final step is applying for and receiving a residential ID card from the Directorates General of Civil Status. The Benefits of Being A Digital Nomad In Oman Your day can be filled with exploring what Oman has to offer in between getting your work done on your laptop. You can have breakfast at Tr.Eat Cafe and get your work done with nearby free Wi-Fi. Then, you can take a break and explore the Sultan Qaboos Grand Mosque in the afternoon before grabbing dinner at Theatrum Restaurant. Plan your itinerary in Oman around your work schedule so that you can still have fun where you are temporarily living while getting your work done. Locating yourself in Muscat would be your best bet as it is the most popular part of Oman with the most free Wi-Fi spots so you can have a variety of places to work. Work can get boring if you are working in the same place every day. Instead of purchasing expensive home Internet, you can plan your day to be located near free Wi-Fi spots to get your work done. No Internet access at home can help you to stay connected to yourself with non-tech activities like reading a book or embarking on a hobby before you go back to being a digital nomad exploring Oman the next day. Where Can I Get Free Wi-Fi in Oman? According to WiFi Map, the top 5 places with free Wi-Fi in Oman are Muscat, Seeb, Salalah, Sohar, and Matrah. Muscat is the most popular region of Oman with free Wi-Fi spots, featuring 2,883 locations to connect with your laptop to complete your workload. When you first enter Muscat or another popular region in Oman with Wi-Fi spots, you can download WiFi Map to your smartphone so you are informed of all the nearby spots where you can get connected. Local hotels, cafes, restaurants, and other businesses could have free Wi-Fi for their patrons. Maybe you want to explore a part of Oman that you have not seen yet. Book a few days at a local hotel and you can utilize the free Wi-Fi there. Whenever you stop at a cafe or restaurant for a meal, you can get some work done after eating before you go to your next destination. Become A Digital Nomad in Oman Today! Oman has so much to offer such as opera houses, mosques, delightful eateries, and forts like the Jibreen Castle. Wadi Bani Khalid is a desert retreat with a mountainous landscape and clear green waters for swimming. When you have to stay connected to work, you can stop by one of the most popular Wi-Fi spots in Muscat. When you want to explore Oman’s attractions and eateries, you can put away your work and enjoy life. Being a digital nomad in Oman can change your life so start the employment visa process today!

Lys234 is one of the residues present in class A β-lactamases that is under selective pressure due to antibiotic use. Located adjacent to proton shuttle residue Ser130, it is suggested to play a role in proton transfer during catalysis of the antibiotics. The mechanism underpinning how substitutions in this position modulate inhibitor efficiency and substrate specificity leading to drug resistance is unclear. The K234R substitution identified in several inhibitor-resistant β-lactamase variants is associated with decreased potency of the inhibitor clavulanic acid, which is used in combination with amoxicillin to overcome β-lactamase–mediated antibiotic resistance. Here we show that for CTX-M-14 β-lactamase, whereas Lys234 is required for hydrolysis of cephalosporins such as cefotaxime, either lysine or arginine is sufficient for hydrolysis of ampicillin. Further, by determining the acylation and deacylation rates for cefotaxime hydrolysis, we show that both rates are fast, and neither is rate-limiting. The K234R substitution causes a 1500-fold decrease in the cefotaxime acylation rate but a 5-fold increase in kcat for ampicillin, suggesting that the K234R enzyme is a good penicillinase but a poor cephalosporinase due to slow acylation. Structural results suggest that the slow acylation by the K234R enzyme is due to a conformational change in Ser130, and this change also leads to decreased inhibition potency of clavulanic acid. Because other inhibitor resistance mutations also act through changes at Ser130 and such changes drastically reduce cephalosporin but not penicillin hydrolysis, we suggest that clavulanic acid paired with an oxyimino-cephalosporin rather than penicillin would impede the evolution of resistance.

Mammalian Asn-linked glycans are extensively processed as they transit the secretory pathway to generate diverse glycans on cell surface and secreted glycoproteins. Additional modification of the glycan core by α-1,6-fucose addition to the innermost GlcNAc residue (core fucosylation) is catalyzed by an α-1,6-fucosyltransferase (FUT8). The importance of core fucosylation can be seen in the complex pathological phenotypes of FUT8 null mice, which display defects in cellular signaling, development, and subsequent neonatal lethality. Elevated core fucosylation has also been identified in several human cancers. However, the structural basis for FUT8 substrate specificity remains unknown.Here, using various crystal structures of FUT8 in complex with a donor substrate analog, and with four distinct glycan acceptors, we identify the molecular basis for FUT8 specificity and activity. The ordering of three active site loops corresponds to an increased occupancy for bound GDP, suggesting an induced-fit folding of the donor-binding subsite. Structures of the various acceptor complexes were compared with kinetic data on FUT8 active site mutants and with specificity data from a library of glycan acceptors to reveal how binding site complementarity and steric hindrance can tune substrate affinity. The FUT8 structure was also compared with other known fucosyltransferases to identify conserved and divergent structural features for donor and acceptor recognition and catalysis. These data provide insights into the evolution of modular templates for donor and acceptor recognition among GT-B fold glycosyltransferases in the synthesis of diverse glycan structures in biological systems.
