The cDNA sequence of beef heart CII-3, a membrane-intrinsic subunit of succinate-ubiquinone oxidoreductase.
We provide the first full-length cDNA and amino acid sequences for beef heart CII-3, one of two hydrophobic subunits that bind succinate dehydrogenase to the mitochondrial inner membrane to form succinate-ubiquinone oxidoreductase (EC 1.3.99.1). Other low molecular weight proteins present in preparations of the isolated complex, including three possible forms of the second anchor polypeptide CII-4, have been identified by amino terminal sequencing.
