Characterization of a cDNA encoding subunit VI of cytochrome c oxidase from the slime mold Dictyostelium discoideum

Biochim Biophys Acta. 1991 Jul 23;1089(3):386-8. doi: 10.1016/0167-4781(91)90180-t.

Abstract

The primary structure of subunit VI of cytochrome c oxidase from the slime mold Dictyostelium discoideum has been determined by sequencing cDNA and N-terminus of the protein. The 92 amino acid residues long polypeptide (Mr = 10,535) shows homology with subunit IV of mammalian and subunit V of yeast cytochrome c oxidase. Though smaller and synthesized without a cleavable presequence, the slime mold oxidase subunit maintains the presence of a putative membrane spanning region.
