General annotation (Comments)

Function

Catalyzes the phosphorylation of pyruvate to phosphoenolpyruvate By similarity.

Catalytic activity

ATP + pyruvate + H2O = AMP + phosphoenolpyruvate + phosphate.

Cofactor

Magnesium By similarity.

Pathway

Carbohydrate biosynthesis; gluconeogenesis.

Domain

The N-terminal domain contains the ATP/Pi binding site, the central domain the pyrophosphate/phosphate carrier histidine, and the C-terminal domain the pyruvate binding site By similarity.

Miscellaneous

The reaction takes place in three steps, mediated by a phosphocarrier 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 By similarity.

Sequence similarities

Belongs to the PEP-utilizing enzyme family.
