Upon EDTA treatment thylakoids lose the chloroplast coupling factor 1 (CF1) part of their ATP synthase, CF0CF1, this exposes the proton channel, CF0. The previously established ability of the CF1 subunit delta to block the proton leak through CF0 prompted us to study (a) the ability of complete CF1 and, for comparison, CF1 lacking the delta subunit to block proton leakage and thereby to reconstitute structurally some photophosphorylation activity of the remaining CF0CF1 molecules and (b) their… CONTINUE READING
