抄録

Branched-chain α-ketoacid dehydrogenase complex (BCKDC) is a rate-limiting enzyme in the branched-chain amino acid catabolic pathway. We have developed a method of BCKDC purification from rat liver using hydrophobic interaction column chromatography (Shimomura et al., Arch. Biochem. Biophys., 283, 293–299 (1990)). Here we report a modification of the method designed to obtain the purified enzyme with high reproducibility.
