DESCRIPTION

Also known as DCMC_HUMAN, MLYCD. Catalyzes the conversion of malonyl-CoA to acetyl-CoA. In the fatty acid biosynthesis MCD selectively removes malonyl-CoA and thus assures that methyl-malonyl-CoA is the only chain elongating substrate for fatty acid synthase and that fatty acids with multiple methyl side chains are produced. In peroxisomes it may be involved in degrading intraperoxisomal malonyl-CoA, which is generated by the peroxisomal beta-oxidation of odd chain-length dicarboxylic fatty acids. Plays a role in the metabolic balance between glucose and lipid oxidation in muscle independent of alterations in insulin signaling. May play a role in controlling the extent of ischemic injury by promoting glucose oxidation. Homotetramer. Dimer of dimers. The two subunits within a dimer display conformational differences suggesting that at any given moment, only one of the two subunits is competent for malonyl-CoA binding and catalytic activity. Under oxidizing conditions, can form disulfide-linked homotetramers (in vitro). Associates with the peroxisomal targeting signal receptor PEX5.
