Other name(s): dolichol phosphomannose-protein mannosyltransferase; protein O-D-mannosyltransferase
Systematic name: dolichyl-phosphate-D-mannose:protein O-D-mannosyltransferase
Comments: The enzyme transfers mannosyl residues to the hydroxy group of serine or threonine residues, producing cell-wall mannoproteins. It acts only on long-chain α-dihydropolyprenyl derivatives, larger than C35.
