Chloride uptake in intact cells of Halobacterium halobium was characterized by rates of influx and efflux of 36Cl- under conditions of light, respiration, or both. Halobacterial mutant strains with and without retinal transport proteins allowed study of the effects of halorhodopsin and bacteriorhodopsin under illumination. Two structurally independent chloride transport systems could be distinguished: halorhodopsin, the already known light-driven chloride pump, and a newly described secondary uptake system, which was energized by respiration or by light via bacteriorhodopsin.
在光照、呼吸或两者并存的条件下,通过³⁶Cl⁻的流入和流出速率对嗜盐栖热菌完整细胞中的氯化物摄取进行了表征。具有和不具有视黄醛转运蛋白的嗜盐细菌突变菌株使得在光照条件下研究嗜盐视紫红质和细菌视紫红质的作用成为可能。可以区分出两个结构独立的氯化物转运系统:嗜盐视紫红质,即已知的光驱动氯化物泵,以及一个新描述的次级摄取系统,该系统通过呼吸作用或经由细菌视紫红质的光来供能。
