Enzyme Information
| 2.3.1.157 | 
							 Glucosamine-1-phosphate N-acetyltransferase. 
							based on mapping to UniProt P9WMN3 		
							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.

| 2.7.7.23 | 
							 UDP-N-acetylglucosamine diphosphorylase. 
							based on mapping to UniProt P9WMN3 		
							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.
