压敏电阻器,anion-selective线粒体频道,VDAC,经历了两个不同的构象变化从开放到封闭状态下积极和消极应用电场。微摩尔的数量的氢氧化铝和其他金属trihydroxides最近被证明能够抑制这种压敏电阻器闭包(莳萝et al。(1987) j .会员。医学杂志。99年,187 - 196;张和Colombini Biochim (1989)。Biophys。学报991年,68 - 78)。建议的抑制结果中和带正电的电压传感器的金属物种。在目前的研究中,通道关闭metal-binding网站的动态研究通过添加(OH) 3只膜的一侧,考察它对渠道的控制过程的影响。铟添加到开放通道抑制通道关闭只有当低含金属方面的潜在应用领域。如果铟是只添加到更高的潜在方面,通道被关闭,并倾向于持续后被废除。 The addition of metal hydroxide after closing the channels with a negative potential on the metal side did not result in channel re-opening as would be expected for sensor neutralization. Inhibition occurred immediately, however, if the channels were first allowed to open briefly. The closed-state selectivity seemed to be very similar in the absence or presence of the metal, indicating that the metal-binding sites are not located within the pore of the channel in the closed conformation. The results are consistent with a voltage-dependent translocation across the membrane of each of two metal-binding sites on VDAC. This translocation is tightly coupled with channel opening and closing.
