IntEnz Enzyme Nomenclature
EC 2.3.1.276

Names

Accepted name:
galactosamine-1-phosphate N-acetyltransferase
Other name:
ST0452 (locus name)
Systematic name:
acetyl-CoA:α-D-galactosamine-1-phosphate N-acetyltransferase

Reaction

Comments:

The enzyme, characterized from the archaeon Sulfolobus tokodaii, is also active toward α-D-glucosamine 1-phosphate (cf. EC 2.3.1.157, glucosamine-1-phosphate N-acetyltransferase). In addition, that enzyme contains a second domain that catalyses the activities of EC 2.7.7.23, UDP-N-acetylglucosamine diphosphorylase, EC 2.7.7.24, glucose-1-phosphate thymidylyltransferase, and EC 2.7.7.83, UDP-N-acetylgalactosamine diphosphorylase.
