- dolichyl phosphate D-mannose + protein dolichyl phosphate + O-D-mannosylprotein
Thus, the two substrates of this enzyme are dolichyl phosphate D-mannose and protein, whereas its two products are dolichyl phosphate and O-D-mannosylprotein.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is dolichyl-phosphate-D-mannose:protein O-D-mannosyltransferase. Other names in common use include dolichol phosphomannose-protein mannosyltransferase, and protein O-D-mannosyltransferase. A human gene that codes for this enzyme is POMT1.
