Comments

Comment Type	Description
Biophysicochemical Properties	Kinetic parameters: KM=1.2 uM for GDP-mannose {ECO:0000269\|PubMed:15548536}; Vmax=25.1 nmol/min/mg enzyme for GDP-mannose {ECO:0000269\|PubMed:15548536}; Note=For the phosphorylated protein, the Vmax increases to 146.7 nmol/min/mg enzyme, whereas the KM stays at 1.1 uM for GDP- mannose, increasing the catalytic efficiency 6-fold.;
Biophysicochemical Properties	Kinetic parameters: KM=1.2 uM for GDP-mannose ; Vmax=25.1 nmol/min/mg enzyme for GDP-mannose ; Note=For the phosphorylated protein, the Vmax increases to 146.7 nmol/min/mg enzyme, whereas the KM stays at 1.1 uM for GDP- mannose, increasing the catalytic efficiency 6-fold.;
Catalytic Activity	GDP-mannose + dolichyl phosphate = GDP + dolichyl D-mannosyl phosphate.
Function	Transfers mannose from GDP-mannose to dolichol monophosphate to form dolichol phosphate mannose (Dol-P-Man) which is the mannosyl donor in pathways leading to N-glycosylation, glycosyl phosphatidylinositol membrane anchoring, and O- mannosylation of proteins.
