Protein attributes

Sequence length469 AA.
Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Function

Catalyzes the irreversible beta-carboxylation of phosphoenolpyruvate (PEP) to form oxaloacetate (OAA), a four-carbon dicarboxylic acid source for the tricarboxylic acid cycle By similarity. HAMAP-Rule MF_01904

Catalytic activity

Phosphate + oxaloacetate = H2O + phosphoenolpyruvate + HCO3-. HAMAP-Rule MF_01904

Cofactor

Magnesium By similarity. HAMAP-Rule MF_01904

Subunit structure

Homotetramer By similarity. HAMAP-Rule MF_01904

Sequence similarities

Belongs to the PEPCase type 2 family.

Sequence caution

The sequence BAA29084.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
