We report the effect of UV-Vis light on the membrane-bound [Ni-Fe] hydrogenase from Aquifex aeolicus under turnover conditions. Using electrochemistry, we show a potential dependent light sensitivity and propose that a light-induced structural change of the [Ni-Fe] active site is related to an enhanced reactivation of the hydrogenase under illumination at high potentials.
我们报告了在周转条件下紫外可见光照对来自水生栖热菌的膜结合 [Ni-Fe] 氢化酶的影响。通过电化学方法,我们发现了一种依赖于电位的光敏感性,并提出光诱导的 [Ni-Fe] 活性中心结构变化与在高电位下光照下氢化酶的增强再激活有关。
