In enzymology a 2-hydroxyacylsphingosine 1-beta-galactosyltransferase (EC 2.4.1.45) is an enzyme that catalyzes the chemical reactionUDP-galactose + 2-(2-hydroxyacyl)sphingosine UDP + 1-(beta-D-galactosyl)-2-(2-hydroxyacyl)sphingosineThus the two substrates of this enzyme are UDP-galactose and 2-(2-hydroxyacyl)sphingosine whereas its two products are UDP and 1-(beta-D-galactosyl)-2-(2-hydroxyacyl)sphingosine.This enzyme belongs to the family of glycosyltransferases specifically the hexosyltransferases.
