Structural analysis of α1,3-linked galactose-containing oligosaccharides in Schizosaccharomyces pombe mutants harboring single and multiple α-galactosyltransferase genes disruptions.

Abstract excerpt

In the fission yeast Schizosaccharomyces pombe, galactose (Gal) residues are transferred to N- and O-linked oligosaccharides of glycoproteins by galactosyltransferases in the lumen of the Golgi apparatus. In S. pombe, the major in vitro α1,2-galactosyltransferase activity has been purified, the gma12(+) gene has been cloned, and three α-galactosyltransferase genes (gmh1(+)-gmh3(+)) have also been partially...
