Galactosylation of cell-surface glycoprotein required for hyphal growth and cell wall integrity in Schizosaccharomyces japonicus.

Schizosaccharomyces japonicus is a dimorphic yeast, transiting between unicellular and hyphal growth. The glycoproteins of fission yeast contain, in addition to mannose (Man), a large number of galactose (Gal) residues. Previously, we reported that the cell-surface O-glycans of S.
