Enzyme Information

2.7.7.23

UDP-N-acetylglucosamine diphosphorylase.

based on mapping to UniProt P43889

UTP + N-acetyl-alpha-D-glucosamine 1-phosphate = diphosphate + UDP-N- acetyl-alpha-D-glucosamine.

-!- Part of the pathway for acetamido sugar biosynthesis in bacteria and archaea. -!- The enzyme from several bacteria (e.g., Escherichia coli, Bacillus subtilis and Haemophilus influenzae) has been shown to be bifunctional and also to possess the activity of EC 2.3.1.157. -!- The enzyme from plants and animals is also active toward N-acetyl- alpha-D-galactosamine 1-phosphate (cf. EC 2.7.7.83), while the bacterial enzyme shows low activity toward that substrate.

2.3.1.157

Glucosamine-1-phosphate N-acetyltransferase.

based on mapping to UniProt P43889

Acetyl-CoA + alpha-D-glucosamine 1-phosphate = CoA + N-acetyl-alpha-D- glucosamine 1-phosphate.

-!- The enzyme from several bacteria has been shown to be bifunctional and also to possess the activity of EC 2.7.7.23.
