MetaCyc Enzyme: 2,3-bisphosphoglycerate-independent phosphoglycerate mutase

Gene: pgm Accession Number: G-3786 (MetaCyc)

Synonyms: PF1959, iPGM

Species: Pyrococcus furiosus

Subunit composition of 2,3-bisphosphoglycerate-independent phosphoglycerate mutase = [Pgm]4
         phosphoglycerate mutase subunit = Pgm

Summary:
The interconversion of 3-phosphoglycerate and 2-phosphoglycerate during glycolysis and gluconeogenesis is catalyzed by phosphoglycerate mutase (PGM). In bacteria and eukaryotes two structurally distinct enzymes have been found, a cofactor-dependent (dPGM) and a cofactor-independent (iPGM) type.

Archaebacteria possess a new family of PGM proteins, distantly related to iPGMs. The P. furiosus enzyme has been cloned and expressed in a heterlogous host, and the activity of a cofactor-independent phosphoglycerate mutase has been confirmed [vanderOost02].
