Protein-O-glycosylation in yeast: protein-specific mannosyltransferases

S.cerevisiae contains at least six genes (PMT1–6) fordolicholphosphate-D-mannose: protein-O-D-mannosyltransferases.The in vivo mannosylation of seven O-mannosylated yeast proteinshas been analyzed in a number of pmt mutants. The results clearlyindicate that the various protein O-mannosyltransferases havedifferent specificities for protein substrates. Five of theproteins tested (chitinase, a-agglutinin, Kre9p, Bar1p, Pir2p/hsp150)are mainly underglycosylated in pmt1 and pmt2 mutants, wherebyqualitative differences exist among the various proteins. Twoof the O-mannosylated proteins (Ggp1p and Kex2p) are not atall affected in pmt1 and pmt2 mutants but are clearly underglycosylatedwhen PMT4 is mutated. Although the PMT4 gene product is shownto be responsible for O-mannosylating a Ser-rich region of Ggp1pin vivo, a penta-seryl-peptide is not an in vitro substratefor this transferase. A PMT3 mutation does affect O-manno-sylationof chitinase only in the genetic background of a pmt1pmt2 doublemutation, indicating that PMT1 and PMT2 can compensate for adeleted PMT3 gene. dolichol-phosphate PMT gene family protein glycosylation S. cerevisiae
