S1PNA_SULTO Bifunctional enzyme involved in the synthesis of UDP-N-acetylglucosamine (UDP-GlcNAc) and UDP-N-acetylgalactosamine (UDP-GalNAc). It has multiple amino-sugar-1-phosphate acetyltransferase activities, including glucosamine-1-phosphate (GlcN-1-P) acetyltransferase and galactosamine-1-phosphate (GalN-1-P) acetyltransferase activities, and multiple sugar-1-phosphate nucleotidylyltransferase activities, including N-acetylglucosamine-1-phosphate (GlcNAc-1-P) uridyltransferase and N-acetylgalactosamine-1-phosphate (GalNAc-1-P) uridyltransferase activities (PubMed:15598657, PubMed:20400541, PubMed:25567746). Also catalyzes the formation of dTDP-glucose from dTTP and glucose-1-phosphate (Glc-1-P), and the reverse reaction, which produces dTTP from dTDP-glucose and diphosphate (PubMed:15598657). Can also catalyze the formation of UDP-glucose from UTP and glucose-1-phosphate (PubMed:27864169, PubMed:30291121).[1][2][3][4][5]
