DE RecName: Full=Enolase {ECO:0000255|HAMAP-Rule:MF_00318}; DE EC=4.2.1.11 {ECO:0000255|HAMAP-Rule:MF_00318}; DE AltName: Full=2-phospho-D-glycerate hydro-lyase {ECO:0000255|HAMAP-Rule:MF_00318}; DE AltName: Full=2-phosphoglycerate dehydratase {ECO:0000255|HAMAP-Rule:MF_00318}; GN Name=eno {ECO:0000255|HAMAP-Rule:MF_00318}; OrderedLocusNames=Bpro_3184; OS Polaromonas sp. (strain JS666 / ATCC BAA-500). OC Bacteria; Pseudomonadota; Betaproteobacteria; Burkholderiales; OC Comamonadaceae; Polaromonas. OX NCBI_TaxID=296591; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=JS666 / ATCC BAA-500; RX PubMed=18723656; DOI=10.1128/aem.00197-08; RA Mattes T.E., Alexander A.K., Richardson P.M., Munk A.C., Han C.S., RA Stothard P., Coleman N.V.; RT "The genome of Polaromonas sp. strain JS666: insights into the evolution of RT a hydrocarbon- and xenobiotic-degrading bacterium, and features of RT relevance to biotechnology."; RL Appl. Environ. Microbiol. 74:6405-6416(2008). 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}.
