Abstract excerpt
A respiratory-defective mutant (C54) of Saccharomyces cerevisiae was found to have a phenotype consistent with a mutation in either mitochondrial protoporphyrinogen oxidase or ferrochelatase. The mutant is grossly deficient in hemes, accumulates protoporphyrin and is rescued by exogenous heme. The increased levels of protoporphyrin at the expense of heme is indicative of a block in one of the two last steps of...
