Bicarbonate requirement for the water-oxidizing complex of photosystem II.
It is well established that bicarbonate stimulates electron transfer between the primary and secondary electron acceptors, Q(A) and Q(B), in formate-inhibited photosystem II; the non-heme Fe between Q(A) and Q(B) plays an essential role in the bicarbonate binding. Strong evidence of a bicarbonate requirement for the water-oxidizing complex (WOC), both O2 evolving and assembling from apo-WOC and...
متن کاملEffect of bicarbonate on the water-oxidizing complex of photosystem II in the super-reduced S-states.
It is shown that the hydrazine-induced transition of the water-oxidizing complex (WOC) to super-reduced S-states depends on the presence of bicarbonate in the medium so that after a 20 min treatment of isolated spinach thylakoids with 3 mM NH(2)NH(2) at 20 degrees C in the CO(2)/HCO(3)(-)-depleted buffer the S-state populations are: 42% of S(-3), 42% of S(-2), 16% of S(-1) and even formal S(-4)...
متن کاملInhibition of the Water Oxidizing Complex of Photosystem II and the Reoxidation of the Quinone Acceptor QA− by Pb2+
The action of the environmental toxic Pb(2+) on photosynthetic electron transport was studied in thylakoid membranes isolated from spinach leaves. Fluorescence and thermoluminescence techniques were performed in order to determine the mode of Pb(2+) action in photosystem II (PSII). The invariance of fluorescence characteristics of chlorophyll a (Chl a) and magnesium tetraphenylporphyrin (MgTPP)...

متن کاملEffects of Bicarbonate Depletion on Secondary Acceptors of Photosystem Ii
In thylakoid membranes incubated in the dark with ferricyanide, an auxiliary acceptor (Q400) associated with Photosystem II becomes oxidized. It has been reported that, based on oxygen flash-yield data, electron flow to Q400 did not occur in 'bicarbonate-depleted' (formate-pretreated) samples. Contrary to this earlier report, we find, based on oxygen flash-yield data and chlorophyll a fluoresce...
