Investigation of the role and mechanism of IF1 and STF1 proteins, twin inhibitory peptides which interact with the yeast mitochondrial ATP synthase.


Inhibition of the yeast F(0)F(1)-ATP synthase by the regulatory peptides IF1 and STF1 was studied using intact mitochondria and submitochondrial particles from wild-type cells or from mutants lacking one or both peptides. In intact mitochondria, endogenous IF1 only inhibited uncoupled ATP hydrolysis and endogenous STF1 had no effect. Addition of alamethicin… (More)
