The branched-chain α-ketoacid dehydrogenase complex (BCKDC or BCKDH complex) is a multi-subunit complex of enzymes that is found on the mitochondrial inner membrane. This enzyme complex catalyzes the oxidative decarboxylation of branched, short-chain alpha-ketoacids. BCKDC is a member of the … See more This complex requires the following 5 coenzymes: • Thiamine pyrophosphate • Lipoate (lipoic acid) • Coenzyme A See more The mechanism of enzymatic catalysis by the BCKDC draws largely upon the elaborate structure of this large enzyme complex. This enzyme complex is composed of three catalytic components: alpha-ketoacid dehydrogenase (also referred to as the … See more A deficiency in any of the enzymes of this complex as well as an inhibition of the complex as a whole leads to a buildup of branched-chain amino acids and their harmful derivatives … See more In animal tissue, BCKDC catalyzes an irreversible step in the catabolism of the branched-chain amino acids L-isoleucine, L-valine, and L-leucine, acting on their deaminated … See more As previously mentioned, BCKDC’s primary function in mammals is to catalyze an irreversible step in the catabolism of branched-chain amino acids. However, the BCKDC has a relatively broad specificity, also oxidizing 4-methylthio-2-oxobutyrate and 2-oxobutyrate … See more • GeneReviews/NCBI/NIH/UW entry on Maple Syrup Urine Disease • • EC 1.2.4.4 See more WebBranched Chain Alpha-Keto Organic Acids.
