||Recombinant human PMM1 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques, 31.9kDa (282aa).
||PMM1 (Phosphomannomutase 1) is an enzyme that involved in the synthesis of the GDP-mannose and dolichol-phosphate-mannose required for a number of critical mannosyl transfer reactions. This enzyme 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. In addition, it may be responsible for the degradation of glucose-1,6-bisphosphate in ischemic brain.
