Display the reaction diagram Show all sequences 1.1.1.305more one activity is to decarboxylate UDP-glucuronic acid to UDP-beta-L-threo-pentopyranosyl-4-ulose in the presence of NAD+. The second activity converts UDP-beta-L-threo-pentopyranosyl-4-ulose and NADH to UDP-xylose and NAD+, albeit at a lower rate. Following decarboxylation, there is stereospecific protonation at the C5pro-R position Ralstonia solanacearum ? - ?
Display the reaction diagram Show all sequences 1.1.1.305more UGA decarboxylase produces NADH and UDP-alpha-D-4-dehyroxylose as products, it can rebind NADH and UDP-alpha-D-4-dehyroxylose to slowly make UDP-alpha-D-xylose Escherichia coli ? - ?
Display the reaction diagram Show all sequences 1.1.1.305more hUXS contains a bound NAD+ cofactor that it recycles by first oxidizing UDP-alpha-D-glucuronic acid, and then reducing the UDP-alpha-D-4-dehydroxylose to produce UDP-alpha-D-xylose Homo sapiens ? - ?

Display the reaction diagram Show all sequences 1.1.1.305UDP-glucuronate + NAD+ ArnA is a bi-functional enzyme, the oxidative decarboxylation of UDP-glucuronic acid is catalyzed by the 345-residue C-terminal domain of ArnA. The 304-residue N-terminal domain catalyzes the N-10-formyltetrahydrofolate-dependent formylation of the 4''-amine of UDP-L-4-amino-4-deoxy-L-arabinose, generating the sugar nucleotide, uridine 5'-diphospho-beta-(4-deoxy-4-formamido-L-arabinose). The two domains of ArnA are expressed independently as active proteins in Escherichia coli. Both are required for maintenance of polymyxin resistance and 4-amino-4-deoxy-L-arabinose modification of lipid A. only the formylated sugar nucleotide is converted in vitro to an undecaprenyl phosphate-linked form by the enzyme ArnC Escherichia coli UDP-beta-L-threo-pentapyranos-4-ulose + CO2 + NADH + H+ - ?
Display the reaction diagram Show all sequences 1.1.1.305UDP-glucuronate + NAD+ ArnA is a key enzyme in the lipid A modification pathway, and its deletion abolishes both the Ara4N-lipid A modification and polymyxin resistance. ArnA is a bifunctional enzyme. It can catalyze the NAD+-dependent decarboxylation of UDP-glucuronic acid to UDP-4-keto-arabinose and the N-10-formyltetrahydrofolate dependent formylation of UDP-4-amino-4-deoxy-L-arabinose Escherichia coli UDP-beta-L-threo-pentapyranos-4-ulose + CO2 + NADH + H+ - ?
Display the reaction diagram Show all sequences 1.1.1.305UDP-glucuronate + NAD+ modification of the lipid A moiety of lipopolysaccharide by the addition of the sugar 4-amino-4-deoxy-L-arabinose is a strategy adopted by pathogenic Gram-negative bacteria to evade cationic antimicrobial peptides produced by the innate immune system. The bifunctional enzyme ArnA is required for 4-amino-4-deoxy-L-arabinose biosynthesis and catalyzes the NAD+-dependent oxidative decarboxylation of UDP-glucuronic acid to generate a UDP-4'-keto-pentose sugar and also catalyzes transfer of a formyl group from N-10-formyltetrahydrofolate to the 4'-amine of UDP-4-amino-4-deoxy-L-arabinose Escherichia coli UDP-beta-L-threo-pentapyranos-4-ulose + CO2 + NADH + H+ - ?
