Glycolysis enolase
WebEnolase (EC 4.2.1.11) catalyzes the reversible dehydration of 2-phosphoglycerate (PGA) to phosphoenolpyruvate (PEP), an essential reaction in both glycolysis and gluconeogenesis. Depending on the species, enolases have other functions, ranging from being a transcription factor in several organisms [1–3] to being a plasminogen receptor on the ... Phosphopyruvate hydratase, usually known as enolase, is a metalloenzyme (EC 4.2.1.11) that catalyses the conversion of 2-phosphoglycerate (2-PG) to phosphoenolpyruvate (PEP), the ninth and penultimate step of glycolysis. The chemical reaction is: 2-phospho-D-glycerate See more In humans there are three subunits of enolase, α, β, and γ, each encoded by a separate gene that can combine to form five different isoenzymes: αα, αβ, αγ, ββ, and γγ. Three of these isoenzymes (all homodimers) are … See more Using isotopic probes, the overall mechanism for converting 2-PG to PEP is proposed to be an E1cB elimination reaction involving a carbanion intermediate. The … See more Small-molecule inhibitors of enolase have been synthesized as chemical probes (substrate-analogues) of the catalytic mechanism of the enzyme and more recently, have been investigated as potential treatments for cancer and infectious diseases. … See more • Enolase at the U.S. National Library of Medicine Medical Subject Headings (MeSH) See more Enolase is a member of the large enolase superfamily. It has a molecular weight of 82,000-100,000 Daltons depending on the isoform. In human alpha enolase, the two subunits are antiparallel in orientation so that Glu of one subunit forms an ionic bond with See more In recent medical experiments, enolase concentrations have been sampled in an attempt to diagnose certain conditions and their severity. For example, higher concentrations of enolase in cerebrospinal fluid more strongly correlated to low-grade astrocytoma than … See more • Holt A, Wold F (December 1961).

WebEnolase (2-phospho-d-glycerate hydrolyase) is a homodimer (MW 88,000) that is inhibited by fluoride, with formation of the magnesium fluorophosphate complex at the active site.This property of fluoride is used to inhibit glycolysis in blood specimens obtained for measurement of glucose concentration. WebInhibiting glycolysis remains an aspirational approach for the treatment of cancer. We have previously identified a subset of cancers harbouring homozygous deletion of the glycolytic enzyme enolase (ENO1) that have exceptional sensitivity to inhibition of its redundant paralogue, ENO2, through a therapeutic strategy known as collateral lethality.
