title: A yeast mitochondrial inner membrane 30K hydrophobic protein: comparison with subunit 32K of the cytochrome BC 1 complex.
abstract: A yeast mitochondrial inner membrane hydrophobic protein 30K has been isolated and compared to subunit 32K of the yeast cytochrome bc 1 complex. Both proteins are translated on mitochondrial ribosomes, have nearly the same molecular weight and similar aminoacid compositions. Comparison was carried out by immunological techniques with specific antibodies, and by studying 3 yeast strains having mutations in the COB region of the mitochondrial DNA. Results show that the two proteins are not identical.
