生化/生理作用
αα-酮戊二酸脱氢酶(α-KGDH)是生物能量学过程的关键酶，是Krebs循环或三羧酸(TCA)循环代谢流的调控物。它通过还原型烟酰胺腺嘌呤二核苷酸(NADH)的释放，催化α-酮戊二酸氧化脱羧为琥珀酰-CoA[1]。这是TCA循环中的限速反应。该反应为呼吸链提供电子，需要硫胺素焦磷酸作为辅因子。[2]反应速率由NAD（烟酰胺腺嘌呤二核苷酸）还原决定。[1]αα-KGDH的最佳pH值范围为6.6-7.4。该酶会被氧化应激抑制并导致代谢缺乏。但α-KGDH又能产生活性氧(ROS)导致氧化应激。α-KGDH缺陷或浓度不够会导致好几种神经退行性疾病，比如阿尔茨海默病。[2][3]
α-Ketoglutarate dehydrogenase is most responsive to alterations in the tumor microenvironment and contributes to the adaptive metabolic response in cancer. Inhibiting α-ketoglutarate dehydrogenase counteracts lung metastasis associated with breast cancer.[6]

It is generally accepted that cyanobacteria have an incomplete tricarboxylic acid (TCA) cycle because they lack 2-oxoglutarate dehydrogenase and thus cannot convert 2-oxoglutarate to succinyl-coenzyme A (CoA). Genes encoding a novel 2-oxoglutarate decarboxylase and succinic semialdehyde dehydrogenase were identified in
