This enzyme belongs to the family of
glycosyltransferases, specifically the hexosyltransferases. The
systematic name of this enzyme class is UDP-galactose:O-beta-D-xylosylprotein 4-beta-D-galactosyltransferase. Other names in common use include UDP-D-galactose:D-xylose galactosyltransferase, UDP-D-galactose:xylose galactosyltransferase, galactosyltransferase I, and uridine diphosphogalactose-xylose galactosyltransferase. This enzyme participates in
chondroitin sulfate biosynthesis and
glycan structures - biosynthesis 1. It employs one
cofactor,
manganese.
