In enzymology a galactose-1-phosphate thymidylyltransferase (EC 2.7.7.32) is an enzyme that catalyzes the chemical reactiondTTP + alpha-D-galactose 1-phosphate diphosphate + dTDP-galactoseThus the two substrates of this enzyme are dTTP and alpha-D-galactose 1-phosphate whereas its two products are diphosphate and dTDP-galactose.This enzyme belongs to the family of transferases specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases).
