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 -!- SUBUNIT: Component of the RNA degradosome, which is a multiprotein
CC complex involved in RNA processing and mRNA degradation.
CC {ECO:0000255|HAMAP-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}.
