Abstract

In isolated thylakoid membranes, the chlooroplast ATP synthetase catalyses high rates of ATP synthesis, but rather low rates of the reverse reactions. However, higher rates of ATP hydrolysis and Pi-ATP exchange can be obtained after activation by energization of the membranes in the presence of thiol reagents (Shavit, 1980). The participation of different enzyme conformations or altered catalytic site(s) in the catalysis of ADP and ATP utilizing reactions has been suggested (Shavit, 1980; Pedersen, 1978). Chemical modification of the isolated and membrane-bound CF1 has been used to study its mechanism of action (Vallejos, 1981).
