Phosphatase Classification: Fold PGM

PGM is short for PhosphoGlycerate Mutase.

It can be classified as below [1, 2]:

  • Monophosphoglycerate mutase (mPGM) - catalyzes the interconversion of 3-phosphoglycerate (3PGA) and 2-phosphoglycerate (2PGA)
    • dependent on 23PGA as a cofactor (dPGM) - found in animal, fungi, and bacteria
    • independent of 23PGA as a cofactor (iPGM) - found in plants, and bacteria
  • Bisphosphoglycerate mutase (bPGM) - catalyzes primarily the interconversion of 1,3-phosphoglycerate (13PGA) and 23PGA

According to SCOP database, the fold contains single superfamily, which include the families below:

  • c.60.1.1: Cofactor-dependent phosphoglycerate mutase
  • c.60.1.2: Histidine acid phosphatase
  • c.60.1.4: 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase, phosphatase domain

According to Pfam database,

dPGM is also known as histidine phosphatase, branch 1.
