Protein
Pyruvate, phosphate dikinase
Gene
ppdK
Organism
Clostridium symbiosum (Bacteroides symbiosus)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Catalyzes the reversible phosphorylation of pyruvate and phosphate. In E.histolytica and C.symbiosus, PPDK functions in the direction of ATP synthesis.

Catalytic activityi

ATP + pyruvate + phosphate = AMP + phosphoenolpyruvate + diphosphate.

Cofactori

Magnesium.

Enzyme regulationi

Activated by light-induced dephosphorylation. Inhibited by dark-induced phosphorylation. Both reactions are catalyzed by PDRP1 By similarity.

Miscellaneous

The reaction takes place in three steps, each mediated by a carrier histidine residue located on the surface of the central domain. The two first partial reactions are catalyzed at an active site located on the N-terminal domain, and the third partial reaction is catalyzed at an active site located on the C-terminal domain. For catalytic turnover, the central domain swivels from the concave surface of the N-terminal domain to that of the C-terminal domain.
