Mitochondrial dysfunction occurs in many neurodegenerative diseases. The alpha-ketoglutarate dehydrogenase complex (KGDHC) catalyzes a key and arguably rate-limiting step of the tricarboxylic acid cycle (TCA). A reduction in the activity of the KGDHC occurs in brains and cells of patients...

Insulin-releasing effects of 2-ketobutyric acid (KB), 2-ketoisocaproic acid (KIC), 2-keto-3-methylvaleric acid (KMV), and 3-phenylpyruvic acid (PP) were examined by using clonal beta cells. Whereas KIC, KMV, and PP dose-dependently initiated insulin secretion and potentiated the effects of 4.2-16.7 mM glucose...

Maple syrup urine disease is a metabolic disorder caused by mutations of the branched chain keto acid dehydrogenase complex, leading to accumulation of alpha-keto acids and their amino acid precursors in the brain. We now report that alpha-ketoisovaleric, alpha-keto-beta-methyl-n-valeric and...

The panB gene that encodes ketopantoate hydroxymethyltransferase has been cloned from Mycobacterium tuberculosis, expressed, and purified to homogeneity. 1H NMR spectroscopy was used to determine the rate of (i) tetrahydrofolate-independent hydroxymethyltransferase chemistry between formaldehyde and alpha-ketoisovalerate and (ii) deuterium exchange...
