Differential stability of two apo-isocytochromes c in the yeast Saccharomyces cerevisiae.

The Journal of biological chemistry - 15 Feb 1990

Dumont M D, Mathews A J, Nall B T, Baim S B, Eustice D C, Sherman F

Abstract excerpt

The yeast Saccharomyces cerevisiae contains two forms of cytochrome c, iso-1-cytochrome c and iso-2-cytochrome c, encoded by the genes CYC1 and CYC7, respectively. The amino acid sequences of these two isozymes are approximately 80% identical. Cyc3- mutants lack both holocytochromes c, because of a deficiency of cytochrome c heme lyase, the enzyme catalyzing covalent attachment of the heme group to apocytochrome...
