CC -!- FUNCTION: Transfers mannose from Dol-P-mannose to Ser or Thr residues
CC on proteins (Probable). Mannosylates an artificial substrate, probably
CC on a Thr residue, upon expression in M.smegmatis. Glycosylation
CC probably requires the Sec-translocation system.
CC {ECO:0000269|PubMed:16081738, ECO:0000305}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a dolichyl beta-D-mannosyl phosphate + L-seryl-[protein] = 3-
CC O-(alpha-D-mannosyl)-L-seryl-[protein] + a dolichyl phosphate + H(+);
CC Xref=Rhea:RHEA:17377, Rhea:RHEA-COMP:9517, Rhea:RHEA-COMP:9527,

CC ChEBI:CHEBI:137323; EC=2.4.1.109;
CC -!- PATHWAY: Protein modification; protein glycosylation.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305|PubMed:16081738};
CC Multi-pass membrane protein {ECO:0000305|PubMed:16081738}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 39 family.
CC {ECO:0000305}.
