General annotation (Comments)

Function

Catalyzes the last two sequential reactions in the de novo biosynthetic pathway for UDP-GlcNAc. Responsible for the acetylation of Glc-N-1-P to give GlcNAc-1-P and for the uridyl transfer from UTP to GlcNAc-1-P which produces UDP-GlcNAc By similarity. HAMAP MF_01631

Catalytic activity

Acetyl-CoA + alpha-D-glucosamine 1-phosphate = CoA + N-acetyl-alpha-D-glucosamine 1-phosphate. HAMAP MF_01631

UTP + N-acetyl-alpha-D-glucosamine 1-phosphate = diphosphate + UDP-N-acetyl-D-glucosamine. HAMAP MF_01631

Cofactor

Binds 1 magnesium ion per subunit By similarity. HAMAP MF_01631

Pathway

Nucleotide-sugar biosynthesis; UDP-N-acetyl-alpha-D-glucosamine biosynthesis; N-acetyl-alpha-D-glucosamine 1-phosphate from alpha-D-glucosamine 6-phosphate (route II): step 2/2. HAMAP MF_01631

Nucleotide-sugar biosynthesis; UDP-N-acetyl-alpha-D-glucosamine biosynthesis; UDP-N-acetyl-alpha-D-glucosamine from N-acetyl-alpha-D-glucosamine 1-phosphate: step 1/1.

Bacterial outer membrane biogenesis; LPS lipid A biosynthesis. HAMAP MF_01631

Subcellular location

Cytoplasm By similarity HAMAP MF_01631.

Sequence similarities

In the N-terminal section; belongs to the N-acetylglucosamine-1-phosphate uridyltransferase family.

In the C-terminal section; belongs to the transferase hexapeptide repeat family.
