Thylakoid energization by light causes destabilization of CF0CF1 so that the peripheral CF1 sector is more readily detached from the membrane by intermediate concentrations of the chaotropic salt NaSCN. Here we have investigated the correlation between the proton gradient-induced change of CF0CF1 interaction and CF0CF1 activation. The results indicate a close relationship between the two phenomena. The effect is most probably due to reduction of the electrostatic interaction between the two subcomplexes CF0 and CF1 as a consequence of protonations in the interface region.
光引起的类囊体通电会导致CF0CF1不稳定，从而使外周CF1部分更容易被中间浓度的离液盐硫氰酸钠从膜上分离。在这里，我们研究了质子梯度诱导的CF0CF1相互作用变化与CF0CF1激活之间的相关性。结果表明这两种现象之间存在密切关系。这种效应很可能是由于界面区域质子化导致两个亚复合物CF0和CF1之间的静电相互作用减弱所致。
