General annotation (Comments)

Function

Catalyzes the last two sequential reactions in the de novo biosynthetic pathway for UDP-N-acetylglucosamine (UDP-GlcNAc). The C-terminal domain catalyzes the transfer of acetyl group from acetyl coenzyme A to glucosamine-1-phosphate (GlcN-1-P) to produce N-acetylglucosamine-1-phosphate (GlcNAc-1-P), which is converted into UDP-GlcNAc by the transfer of uridine 5-monophosphate (from uridine 5-triphosphate), a reaction catalyzed by the N-terminal domain By similarity. HAMAP-Rule MF_01631

Catalytic activity

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

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

Cofactor

Binds 1 magnesium ion per subunit By similarity.

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-Rule 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-Rule MF_01631

Subunit structure

Homotrimer By similarity.

Subcellular location

Cytoplasm By similarity.

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.
