B. Cochran et al., THE CDNA SEQUENCE OF BEEF-HEART C-II-3, A MEMBRANE-INTRINSIC SUBUNIT OF SUCCINATE-UBIQUINONE OXIDOREDUCTASE, Biochimica et biophysica acta. Bioenergetics, 1188(1-2), 1994, pp. 162-166
We provide the first full-length cDNA and amino acid sequences for bee
f heart C-II-3, one of two hydrophobic subunits that bind succinate de
hydrogenase to the mitochondrial inner membrane to form succinate-ubiq
uinone oxidoreductase (EC 1.3.99.1). Other low molecular weight protei
ns present in preparations of the isolated complex, including three po
ssible forms of the second anchor polypeptide C-II-4, have been identi
fied by amino terminal sequencing.
