CC   -!- FUNCTION: Catalyzes the reversible conversion of 2-phosphoglycerate
CC       into phosphoenolpyruvate. It is essential for the degradation of
CC       carbohydrates via glycolysis. {ECO:0000255|HAMAP-Rule:MF_00318}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(2R)-2-phosphoglycerate = H2O + phosphoenolpyruvate;
CC         Xref=Rhea:RHEA:10164, ChEBI:CHEBI:15377, ChEBI:CHEBI:58289,
CC         ChEBI:CHEBI:58702; EC=4.2.1.11; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00318};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00318};
CC   -!- ACTIVITY REGULATION: The covalent binding to the substrate causes
CC       inactivation of the enzyme, and possibly serves as a signal for the
CC       export of the protein. {ECO:0000255|HAMAP-Rule:MF_00318}.
CC   -!- PATHWAY: Carbohydrate degradation; glycolysis; pyruvate from D-
CC       glyceraldehyde 3-phosphate: step 4/5. {ECO:0000255|HAMAP-
CC       Rule:MF_00318}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00318}.
CC       Secreted {ECO:0000255|HAMAP-Rule:MF_00318}. Cell surface
CC       {ECO:0000255|HAMAP-Rule:MF_00318}. Note=Fractions of enolase are
CC       present in both the cytoplasm and on the cell surface. The export of
CC       enolase possibly depends on the covalent binding to the substrate; once
CC       secreted, it remains attached to the cell surface. {ECO:0000255|HAMAP-
CC       Rule:MF_00318}.
CC   -!- SIMILARITY: Belongs to the enolase family. {ECO:0000255|HAMAP-
CC       Rule:MF_00318}.
