Protein attributes

Sequence length612 AA.
Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Function

Catalyzes the conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP), the rate-limiting step in the metabolic pathway that produces glucose from lactate and other precursors derived from the citric acid cycle By similarity. HAMAP-Rule MF_00452

Catalytic activity

GTP + oxaloacetate = GDP + phosphoenolpyruvate + CO2. HAMAP-Rule MF_00452

Cofactor

Binds 1 manganese ion per subunit By similarity.

Pathway

Carbohydrate biosynthesis; gluconeogenesis. HAMAP-Rule MF_00452

Subunit structure

Monomer By similarity.

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the phosphoenolpyruvate carboxykinase [GTP] family.

Sequence caution

The sequence BAC19501.1 differs from that shown. Reason: Erroneous initiation.
