two forms of yeast cytochrome c synthetases with different specificities were resolved , one ( synthetase i ) , solubilized from mitochondria or the cell debris with triton x-100 , recognizing not horse apocytochrome c but yeast apo-iso-1-cytochrome c as a substrate and the other ( synthetase ii ) still bound with the particulate fraction from mitochondria after treatment with triton , recognizing both horse and yeast apocytochromes c .
