In enzymology an UDP-glucose—hexose-1-phosphate uridylyltransferase (EC 2.7.7.12) is an enzyme that catalyzes the chemical reactionUDP-glucose + alpha-D-galactose 1-phosphate alpha-D-glucose 1-phosphate + UDP-galactoseThus the two substrates of this enzyme are UDP-glucose and alpha-D-galactose 1-phosphate whereas its two products are alpha-D-glucose 1-phosphate and UDP-galactose.This enzyme belongs to the family of transferases specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases).
