Mitochondrial 2-methyl branched chain acyl-CoA dehydrogenase (ACADSB) catalyzes the reaction of alpha-methylbutyryl-CoA and FAD to form 'tiglyl-CoA and FADH2 (Andresen et al. 2000; Gibson et al. 2000). Unpublished crystallographic data (PDB 2JIF) indicate that the enzyme is a tetramer of ACADSB polypeptides whose aminoterminal 51 residues, a mitochondrial targeting sequence, have been removed.
