ATP binding to bovine heart cytochrome c oxidase. A photoaffinity labelling study

C Montecucco et al. Biochem J. .

Abstract

ATP influences the kinetic properties of cytochrome c oxidase. A photoactivatable radioactive ATP analogue was used to localize the nucleotide-binding site on the bovine heart enzyme. Subunits IV and VIII were specifically labelled, suggesting that these two nuclear-coded polypeptides may play a regulatory role on the oxidase functions.
