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.
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 .
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 archaeal cell surface (By similarity).
SIMILARITY: Belongs to the enolase family.
