Comparison of the Primary Structures of Cytochromes c from Wild and Respiration-deficient Mutant Yeasts

The primary structures of the cytochromes c from Saccharomyces oviformis, S. cerevisiae and their respiration-deficient mutants were compared by the criteria of the chromatograms on Amberlite CG-50 columns, amino acid compositions and peptide maps of the tryptic digests. It was concluded that these strains contained a cytochrome c of the same primary structure.
