Protein
UDP-N-acetylglucosamine 2-epimerase
Organism
Neisseria meningitidis serogroup A / serotype 4A (strain Z2491)
Function
Catalyzes the interconversion between UDP-N-acetylglucosamine (UDP-GlcNAc) and UDP-N-acetylmannosamine (UDP-ManNAc). Involved in the biosynthesis of the capsular polysaccharides. In vitro, can also use several chemoenzymatically synthesized UDP-ManNAc derivatives as substrates, with lower efficiency.
Similarity
Belongs to the UDP-N-acetylglucosamine 2-epimerase family.
