physiological function
involved in biosynthesis of N-acetyl-L-fucosamine. Enzyme Cap5E catalyzes 4,6-dehydration of UDP-N-acetyl-Dglucosamine and 3- and 5-epimerization to yield a mixture of three keto-deoxy-sugars. UDP-2-acetamido-2,6-dideoxy-beta-L-arabino-4-hexulose is subsequently reduced at C4 to UDP-2-acetamido-2,6-dideoxy-L-talose by Cap5F. Incubation of UDP-2-acetamido-2,6-dideoxy-L-talose with Cap5G results in 2-epimerization to N-acetyl-L-fucosamine
