RC STRAIN=PRwf-1; RG US DOE Joint Genome Institute; RA Copeland A., Lucas S., Lapidus A., Barry K., Detter J.C., RA Glavina del Rio T., Hammon N., Israni S., Dalin E., Tice H., RA Pitluck S., Chain P., Malfatti S., Shin M., Vergez L., Schmutz J., RA Larimer F., Land M., Hauser L., Kyrpides N., Kim E., Tiedje J., RA Richardson P.; RT "Complete sequence of chromosome of Psychrobacter sp. PRwf-1."; RL Submitted (MAY-2007) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Catalyzes the last two sequential reactions in the de CC novo biosynthetic pathway for UDP-GlcNAc. Responsible for the CC acetylation of Glc-N-1-P to give GlcNAc-1-P and for the uridyl CC transfer from UTP to GlcNAc-1-P which produces UDP-GlcNAc (By CC similarity). CC -!- CATALYTIC ACTIVITY: Acetyl-CoA + alpha-D-glucosamine 1-phosphate = CC CoA + N-acetyl-alpha-D-glucosamine 1-phosphate. CC -!- CATALYTIC ACTIVITY: UTP + N-acetyl-alpha-D-glucosamine 1-phosphate CC = diphosphate + UDP-N-acetyl-D-glucosamine. CC -!- COFACTOR: Binds 1 magnesium ion per subunit (By similarity). CC -!- PATHWAY: Nucleotide-sugar biosynthesis; UDP-N-acetyl-alpha-D- CC glucosamine biosynthesis; N-acetyl-alpha-D-glucosamine 1-phosphate CC from alpha-D-glucosamine 6-phosphate (route II): step 2/2. CC -!- PATHWAY: Nucleotide-sugar biosynthesis; UDP-N-acetyl-alpha-D- CC glucosamine biosynthesis; UDP-N-acetyl-alpha-D-glucosamine from N- CC acetyl-alpha-D-glucosamine 1-phosphate: step 1/1. CC -!- PATHWAY: Bacterial outer membrane biogenesis; LPS lipid A CC biosynthesis. CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- SIMILARITY: In the N-terminal section; belongs to the N- CC acetylglucosamine-1-phosphate uridyltransferase family. CC -!- SIMILARITY: In the C-terminal section; belongs to the transferase CC hexapeptide repeat family.
