In enzymology, a glucosaminylgalactosylglucosylceramide beta-galactosyltransferase is an enzyme that catalyzes the chemical reaction
UDP-galactose + N-acetyl-beta-D-glucosaminyl-(1->3)-beta-D-galactosyl-(1->4)-beta-D- glucosyl-(11)-ceramide
\rightleftharpoons
The 3 substrates of this enzyme are UDP-galactose, N-acetyl-beta-D-glucosaminyl-(1->3)-beta-D-galactosyl-(1->4)-beta-D-, and glucosyl-(11)-ceramide, whereas its 3 products are UDP, beta-D-galactosyl-(1->3)-N-acetyl-beta-D-glucosaminyl-(1->3)-beta-D-, and galactosyl-(1->4)-beta-D-glucosyl-(11)-ceramide.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-galactose:N-acetyl-beta-D-glucosaminyl-(1->3)-beta-D-galactosyl- (1->4)-beta-D-glucosylceramide 3-beta-D-galactosyltransferase. Other names in common use include uridine, diphosphogalactose-acetyl-glucosaminylgalactosylglucosylceramide, galactosyltransferase, GalT-4, paragloboside synthase, glucosaminylgalactosylglucosylceramide 4-beta-galactosyltransferase, lactotriaosylceramide 4-beta-galactosyltransferase, UDP-galactose:N-acetyl-D-glucosaminyl-1,3-D-galactosyl-1,4-D-, glucosylceramide beta-D-galactosyltransferase, and UDP-Gal:LcOse3Cer(beta 1-4)galactosyltransferase.
