The cDNA sequence of beef heart CII-3, a membrane-intrinsic subunit of succinate-ubiquinone oxidoreductase

Biochim Biophys Acta. 1994 Nov 1;1188(1-2):162-6. doi: 10.1016/0005-2728(94)90035-3.


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 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.
