Characterization of aliphatic amine 1,4-diazobicyclo (2,2,2) octane-induced stimulation of beet spinach thylakoid electron transport. Indian Journal of Biochemistry & Biophysics. 1992 Dec; 29(6): 490-3http://imsear.searo.who.int/handle/123456789/27933Electron transport activity of beet spinach thylakoids was enhanced in the presence of aliphatic amine, DABCO (1,4-diazobicyclo (2,2,2) octane), a hydrophilic proton trapping agent. The extent of stimulation was pH-dependent and similar to the effect of the uncoupler ammonium chloride on electron transport. The stimulation of whole-chain (H2O-->MV) electron transport activity was observed only at high (rate-saturating) light intensity. The light-induced proton uptake coupled to electron transport of thylakoid was also arrested by DABCO, suggesting that DABCO uncouples thylakoid phosphorylation by proton trapping.engChloroplasts --drug effectsElectron Transport --drug effectsIntracellular Membranes --drug effectsKineticsPiperazines --pharmacologyPlants --metabolismRadiation-Protective Agents --pharmacologyJournal Article
