Abstract
The rat liver E1β subunit of the branched-chain α-ketoacid dehydrogenase complex has been cloned and sequenced. The amino acid sequence is highly conserved between rat, human and bovine forms of the protein. The β subunits of the branched-chain α-ketoacid dehydrogenase complex from rat and Pseudomonas putida, and the pyruvate dehydrogenase complex from human and Bacillus subtilis show sequence similarities which are shared with two other thiamine pyrophosphate-dependent enzymes, yeast (Hansenula polymorpha) formaldehyde transketolase and human transketolase. These similarities suggest that the β subunits may be involved in thiamine pyrophosphate binding.
