WebJun 1, 2005 · ABSTRACT. The branched-chain amino acids (BCAAs) are required for protein synthesis and neurotransmitter synthesis. The branched-chain α-ketoacid dehydrogenase complex (BCKDC) is the most important regulatory enzyme in the catabolic pathways of the BCAAs. WebPyruvate dehydrogenase complexes share many similarities with branched chain 2-oxoacid dehydrogenase (BCOADH), particularly in their substrate specificity for alpha-keto acids. Specifically, BCOADH catalyzes the degradation of amino acids and these enzymes would have been prevalent during the periods on prehistoric earth dominated by rich …
WebThe branched-chain alpha-keto dehydrogenase complex catalyzes the overall conversion of alpha-keto acids to acyl-CoA and CO 2. It contains multiple copies of three enzymatic components: branched-chain alpha-keto acid decarboxylase (E1), lipoamide acyltransferase (E2) and lipoamide dehydrogenase (E3). 1 publication WebBranched-chain alpha-keto acid dehydrogenase (EC2.6.1.42) is the key regulatory enzyme for Val metabolism, which helps preserve this essential amino acid for protein synthesis during starvation.
