Organism

Aeropyrum pernix (strain ATCC 700893 / DSM 11879 / JCM 9820 / NBRC 100138 / K1) [Complete proteome] [HAMAP]

Taxonomic identifier

272557 [NCBI]

Taxonomic lineage

Archaea › Crenarchaeota › Thermoprotei › Desulfurococcales › Desulfurococcaceae › Aeropyrum

Protein attributes

Sequence length	432 AA.
Sequence status	Complete.
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. HAMAP MF_00318
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. HAMAP MF_00318
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 archaeal cell surface By similarity. HAMAP MF_00318
Sequence similarities	Belongs to the enolase family.
