In enzymology a glycosaminoglycan galactosyltransferase (EC 2.4.1.74) is an enzyme that catalyzes the chemical reactionUDP-galactose + glycosaminoglycan UDP + D-galactosylglycosaminoglycanThus the two substrates of this enzyme are UDP-galactose and glycosaminoglycan whereas its two products are UDP and D-galactosylglycosaminoglycan.This enzyme belongs to the family of glycosyltransferases specifically the hexosyltransferases.
