UTP + a monosaccharide 1-phosphate diphosphate + UDP-monosaccharide

Thus, the two substrates of this enzyme are UTP and monosaccharide 1-phosphate, whereas its two products are diphosphate and UDP-monosaccharide.

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases). The systematic name of this enzyme class is '. Other names in common use include UDP-sugar pyrophosphorylase', and PsUSP.
