Currently, α-ketoglutaric acid (α-KG) is industrially produced by multi-step chemical synthesis, which can cause heavy environmental pollution. Here we reported a simple one-step approach for the production of α-KG by transforming l-glutamic acid with an engineered l-amino acid deaminase (l-AAD)

Quantification of 2-ketoglutaric acid in plasma and cerebrospinal fluid as its O-trimethylsilyl++-quinoxalinol derivative by gas chromatography chemical ionization mass spectrometry is described with benzoylformic acid as internal standard. This technique, with ammonia as reactant gas, only detects the protonated molecular

Genetic up-regulation of mitochondrial 2-oxoglutarate dehydrogenase is known to increase reactive oxygen species, being detrimental for cancer cells. Thiamine diphosphate (ThDP, cocarboxylase) is an essential activator of the enzyme and inhibits p53-DNA binding in cancer cells. We hypothesize that the
