In enzymology a sphingosine beta-galactosyltransferase (EC 2.4.1.23) is an enzyme that catalyzes the chemical reactionUDP-galactose + sphingosine UDP + psychosineThus the two substrates of this enzyme are UDP-galactose and sphingosine whereas its two products are UDP and psychosine.This enzyme belongs to the family of glycosyltransferases specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-galactose:sphingosine 1-beta-galactosyltransferase.
