Inhibitory effect of peroxyacetyl nitrate on cyclic photophosphorylation by chloroplasts from black valentine bean leaves.
The inhibitory effect of peroxyacetyl nitrate on the cyclic photophosphorylation of chloroplasts isolated from Black Valentine variety bean leaves (Phaseolis vulgaris L.) has been studied. Peroxyacetyl nitrate caused inhibition to photophosphorylation, in either the dark or the light, by affecting the chloroplast. Evidence is presented which suggests that peroxyacetyl nitrate could oxidize sulf...
متن کاملDesaspidin and CO(2) Fixation by Spinach Chloroplasts.
Baltscheffsky and de Kiewiet (1) proposed that desaspidin uncoupled photosynthetic phosphorylation in spinach chloroplasts. Arnon and coworkers (2, 3) have extended this work and on the basis of their finding that 1 ttm desaspidin inhibited cyclic phosphorylation completely while not affecting noncyclic phosphorylation, claim that desaspidin is a specific uncouipler at the site of cyclic phosph...

متن کاملEffect of antimycin a on photosynthesis of intact spinach chloroplasts.
Low concentrations (0.5-10 mum) of antimycin A were shown to increase the rate of CO(2) fixation, O(2) evolution and inorganic phosphate esterification in intact spinach (Spinacia oleracea) chloroplasts. The increase was highest when the light intensity was saturating. Stimulation was independent of the bicarbonate concentration and was accompanied by an enhancement in the synthesis of glycerat...
