Abstract excerpt
Cytochrome c oxidase isolated from a wild-type yeast strain and a mutant in which the gene for subunit VIa had been disrupted were used to study the interaction of adenine nucleotides with the enzyme complex. At low ionic strength (25 mM potassium phosphate), in the absence of nucleotides, the cytochrome c oxidase activity of the mutant enzyme lacking subunit VIa was higher than that of the wild-type enzyme....
