Protein attributes

Sequence length430 AA.
Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Function

Catalyzes the reversible conversion of 2-phosphoglycerate into phosphoenolpyruvate. It is essential for the degradation of carbohydrates via glycolysis By similarity. HAMAP-Rule MF_00318

Catalytic activity

2-phospho-D-glycerate = phosphoenolpyruvate + H2O. HAMAP-Rule MF_00318

Cofactor

Magnesium By similarity. HAMAP-Rule MF_00318

Enzyme regulation

The covalent binding to the substrate causes inactivation of the enzyme, and possibly serves as a signal for the export of the protein By similarity. HAMAP-Rule MF_00318

Pathway

Carbohydrate degradation; glycolysis; pyruvate from D-glyceraldehyde 3-phosphate: step 4/5. HAMAP-Rule MF_00318

Subcellular location

Cytoplasm By similarity. Secreted By similarity. Cell surface By similarity. Note: Fractions of enolase are present in both the cytoplasm and on the cell surface. The export of enolase possibly depends on the covalent binding to the substrate; once secreted, it remains attached to the cell surface By similarity. HAMAP-Rule MF_00318

Sequence similarities

Belongs to the enolase family.
