This family includes the galactosyltransferases UDP-galactose:2-acetamido-2-deoxy-D-glucose3beta-galactosyltransferas e Swiss:O43825 [1] and UDP-Gal:beta-GlcNAc beta 1,3-galactosyltranferase Swiss:O54904 [2]. Specific galactosyltransferases transfer galactose to GlcNAc terminal chains in the synthesis of the lacto-series oligosaccharides types 1 and 2 [1].
