Abstract:
ADP phosphorylation up to 2.5 nmol per mg of chlorphyll has been found in chloroplasts from Vicia faba plants when the suspension was sharply acidified from pH 8 to pH 1.6 with excess of HC1/KC1 solution. This fact appears to be due to confromation relaxation of the coupling factor under acid-induced denaturation. Heat pretreatment inhibits this effect.
