Biochem/physiol Actions

(±)-3-Methyl-2-oxovaleric acid sodium salt is a mixture of the D- and L-3-methyl-2-oxovaleric acids. 3-methyl-2-oxovaleric acid is used as a substrate to study the specificity, distribution and kinetics of α-keto acid dehydrogenases. α-keto-β-methylvaleric acid is used to inhibit the mitochondrial α-ketoglutarate dehydrogenase complex (KGDHC) to induce and study nerve cell death. α-keto-β-methylvaleric acid may be studied as a reactive oxygen scavenger.

The present study investigated (1) the free amino acid (FAA) composition in semen of rainbow trout Oncorhynchus mykiss and carp Cyprinus carpio, (2) enzyme systems involved in amino acid metabolism and (3) the effect of amino acids on sperm viability

The bacteriocin, lacticin 3147, increased isoleucine transamination by Lactococcus lactis IFPL359 in a cheese model system. The formation of alpha-keto-beta-methyl-n-valeric acid and 2-hydroxy-3-methyl-valeric acid increased by three times in cheese slurries at 12 degrees C and cheese aroma intensity increased

The alpha-ketoglutarate dehydrogenase complex (KGDHC) is a mitochondrial enzyme in the TCA cycle. Inhibition of KGDHC activity by alpha-keto-beta-methyl-n-valeric acid (KMV) is associated with neuron death. However, the effect of KMV in microglia is unclear. Therefore, we investigated the effect

Mitochondrial dysfunction has been implicated in cell death in many neurodegenerative diseases. Diminished activity of the alpha-ketoglutarate dehydrogenase complex (KGDHC), a key and arguably rate-limiting enzyme of the Krebs cycle, occurs in these disorders and may underlie decreased brain metabolism.

Gene duplication is a key evolutionary mechanism providing material for the generation of genes with new or modified functions. The fate of duplicated gene copies has been amply discussed and several models have been put forward to account for duplicate
