This work aims to produce α-ketoisocaproate (KIC) from L-leucine via the free-whole-cell biotransformation of Rhodococcus opacus DSM 43250. The effects of temperature, pH, substrate concentration, cell concentration, and rotating speed on KIC production were examined. Furthermore, the biotransformation conditions were

Amino acids such as leucine and its metabolite α-ketoisocaproate (KIC), are returning to be the focus of studies, mainly because of their anti-catabolic properties, through inhibition of muscle proteolysis and enhancement of protein synthesis. It is clear that these effects

Branched-chain aminotransferases (BCAT), which utilize pyridoxal 5'-phosphate (PLP) as a cofactor, reversibly catalyze the transfer of the α-amino groups of three of the most hydrophobic branched-chain amino acids (BCAA), leucine, isoleucine, and valine, to α-ketoglutarate to form the respective branched-chain
