Beta1,2-xylosyltransferase Cxt1p is solely responsible for xylose incorporation into Cryptococcus neoformans glycosphingolipids.

ABSTRACT: The Manalpha1,3(Xylbeta1,2)Manalpha structural motif is common to both capsular polysaccharides of Cryptococcus neoformans and to cryptococcal glycosphingolipids. Comparative analysis of glycosphingolipid structural profiles in wild-type and mutant strains showed that the Xylbeta1,2-transferase (Cxt1p) that participates in capsular polysaccharide biosynthesis is also the sole transferase responsible for adding xylose to C. neoformans glycosphingolipids.
