Phosphomannomutase 1 is an enzyme that in humans is encoded by the PMM1 gene.[1][2][3]


Phosphomannomutase catalyzes the conversion between D-mannose 6-phosphate and D-mannose 1-phosphate which is a substrate for GDP-mannose synthesis. GDP-mannose is used for synthesis of dolichol-phosphate-mannose, which is essential for N-linked glycosylation and thus the secretion of several glycoproteins as well as for the synthesis of glycosyl-phosphatidyl-inositol (GPI) anchored proteins.[3]


This enzyme has been extracted from the venom of the wasp species Polistes major major. [4]
