Secondary Accession Numbers
  • 6931
Name Phosphomannomutase 1
  1. PMM 1
  2. PMMH-22
Gene Name PMM1
Protein Type Enzyme
Biological Properties
General Function Involved in metal ion binding
Specific Function Involved in the synthesis of the GDP-mannose and dolichol-phosphate-mannose required for a number of critical mannosyl transfer reactions. In addition, may be responsible for the degradation of glucose-1,6-bisphosphate in ischemic brain.
