Protein attributes

Sequence length	426 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred 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.
Catalytic activity	2-phospho-D-glycerate = phosphoenolpyruvate + H2O. HAMAP MF_00318
Cofactor	Magnesium. Required for catalysis and for stabilizing the dimer By similarity.
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.
Pathway	Carbohydrate degradation; glycolysis; pyruvate from D-glyceraldehyde 3-phosphate: step 4/5. HAMAP MF_00318
Subcellular location	Cytoplasm. Secreted. Cell surface. 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.
Sequence similarities	Belongs to the enolase family.
