烯醇酶(Enolase,ENO)是一种催化2一磷酸-D甘油酸和磷酸烯醇式丙酮酸在糖酵解途径相互转化的二聚体酶。具有3个免疫亚单位:α、β和γ;构成5种同功酶:αα、ββ、γγ,αβ及γ。神经胶质细胞仅含ααEMO,γγ限于神经元。缺血性神经元极少或不含 ENO,可能因酶释放到细胞外间隙并进入脑脊液(CSF)。对脑血管意外 CSF 中肌酸激酶(CK),谷草转氨酶(GOT),乳酸脱氢酶(LDH), Enolase (ENO) is a dimeric enzyme that catalyzes the interconversions of 2-monophosphate-D-glycerate and phosphoenolpyruvate in the glycolysis pathway. Has three immune subunits: α, β and γ; constitutes five kinds of isozymes: αα, ββ, γγ, αβ and γ. Glial cells contain only αα EMO, γγ limited to neurons. Ischemic neurons have little or no ENO and may release into the extracellular space and into the cerebrospinal fluid (CSF). In cerebrovascular accidental CSF creatine kinase (CK), aspartate aminotransferase (GOT), lactate dehydrogenase (LDH)
