MetaCyc Enzyme: pyruvate, water dikinase

Species: Desulfobacter hydrogenophilus

Subunit composition of pyruvate, water dikinase = [pyruvate, water dikinase monomer]

Summary:
Information on the subunit structure of this protein from Desulfobacter hydrogenophilus is not available.

Locations: cytosol

In Reactions of unknown directionality:

Not in pathways:
a pyruvate,water dikinase + ADP = [a pyruvate, water dikinase]-phosphate + AMP + H+
[a pyruvate, water dikinase]-phosphate + phosphate + H+ = a pyruvate,water dikinase + diphosphate

Gene-Reaction Schematic: ?

GO Terms:

Cellular Component: GO:0005829 - cytosol [Schauder87]


Enzymatic reaction of: pyruvate, water dikinase

Synonyms: phosphoenolpyruvate synthase

EC Number: 2.7.9.2

pyruvate + ATP + H2O <=> phosphoenolpyruvate + AMP + phosphate + 2 H+

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction of enzyme catalysis.

The reaction is physiologically favored in the direction shown.

In Pathways: reductive TCA cycle I

Summary:
This reaction forms phosphoenolpyruvate, required for gluconeogenesis [Beh93]. Enzyme activity was assayed in cell-free extracts at 30 deg. C, under anaerobic conditions [Schauder87].
