UDP-N-acetylglucosamine 4,6-dehydratase (configuration-retaining)
UDP-N-acetylglucosamine 4,6-dehydratase (configuration-retaining) (EC 4.2.1.135, PglF) is an enzyme with systematic name UDP-N-acetyl-alpha-D-glucosamine hydro-lyase (configuration-retaining; UDP-2-acetamido-2,6-dideoxy-alpha-D-xylo-hex-4-ulose-forming).[1][2] This enzyme catalyses the following chemical reaction
- UDP-N-acetyl-alpha-D-glucosamine UDP-2-acetamido-2,6-dideoxy-alpha-D-xylo-hex-4-ulose + H2O
