In enzymology an UTP—hexose-1-phosphate uridylyltransferase (EC 2.7.7.10) is an enzyme that catalyzes the chemical reactionUTP + alpha-D-galactose 1-phosphate diphosphate + UDP-galactoseThus the two substrates of this enzyme are UTP and alpha-D-galactose 1-phosphate whereas its two products are diphosphate and UDP-galactose.This enzyme belongs to the family of transferases specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases).
