BRITE hierarchy
Reaction(IUBMB)
UTP + a monosaccharide 1-phosphate = diphosphate + UDP-monosaccharide [RN:
R08845 ]
Reaction(KEGG)
Substrate
Product
Comment
Requires Mg2+ or Mn2+ for maximal activity. The reaction can occur in either direction and it has been postulated that MgUTP and Mg-diphosphate are the actual substrates [1,2]. The enzyme catalyses the formation of UDP-Glc, UDP-Gal, UDP-GlcA, UDP-L-Ara and UDP-Xyl, showing broad substrate specificity towards monosaccharide 1-phosphates. Mannose 1-phosphate, L-Fucose 1-phosphate and glucose 6-phosphate are not substrates and UTP cannot be replaced by other nucleotide triphosphates [1].
