Effects of α-benzyl-α-bromo-malodinitrile on the primary electron acceptor of Photosystem II in spinach chloroplasts

Energy Conservation in Photosynthetic Electron Transport of Chloroplasts

“…Miles et al (203), however, reported that the photoreduction of Hg++ is DCMU insensitive. Brandon suggested from the effects of a-benzyl-a-bromo-malodinitrile on photosystem II that the compound may be also a DCMU insensitive acceptor of photosystem II (53).…”

Modification of oxygen evolving center by Tris-washing

“…Chloroplasts were uncoupled by Tris-washing at pH 7.2 [104]. Scince the discovery of Tris-inactivating effect on chloroplasts [i], Tris-washed chloroplasts and their particles were the good subject to study (A), light-induced electron transport in the presence of artificial electron donors such as TCPIP.H 2 [i], DCPIP-H 2 [3][4]123], phenylenediamine [4, 9, 37, 59, 64-65, 81, 83, 86, 91, 113-114], hydroquinone [8, i0, 22, 37-38, 51-52, 81, 83, 86, 115-116], benzidine [8,64,86,[113][114], semicarbazide [8,113], diphenylcarbazide [38][39][40][41][42][43][44]54], ascorbate [9,37,79,[86][87], Mn 2+ [i0, 50,52,54,64,[83][84], H202 [46][47][48], hydrazobenzene [44] and tetraphenylboron [45,54], (B). variable fluorescence [4-5, 8, I0, 12, 22, 33, 46, 50-61, 123] and delayed light emission (delayed fluorescence, luminescence) [27,52,[60][61][62][63]…”
