UDP-N-acetylglucosamine 4,6-dehydratase (configuration-inverting) ( EC 4.2.1.115, FlaA1, UDP-N-acetylglucosamine 5-inverting 4,6-dehydratase, PseB, UDP-N-acetylglucosamine hydro-lyase (inverting, UDP-2-acetamido-2,6-dideoxy-β-L)arabino-hex-4-ulose-forming)) is an enzyme with systematic name UDP-N-acetyl-α-D-glucosamine hydro-lyase (inverting; UDP-2-acetamido-2,6-dideoxy-β-L-arabino-hex-4-ulose-forming). [1] [2] [3] This enzyme catalyses the following chemical reaction
- UDP-N-acetyl-α-D-glucosamine UDP-2-acetamido-2,6-dideoxy-β-L-arabino-hex-4-ulose + H2O
This enzyme contains NADP+ as a cofactor.
