Abstract
Reaction of purple membrane with water soluble carbodiimides inhibits the spectral transition from purple to blue observed at acid pH. The pK and Hill constant for this transition are shifted from 3.4 to 2.6 and from 1.8 to 0.85, respectively. The results suggest a connection between the uptake side of the proton pump and the purple-to-blue transition.
摘要
紫膜与水溶性碳二亚胺的反应抑制了在酸性pH条件下观察到的从紫色到蓝色的光谱转变。这种转变的pK值和希尔常数分别从3.4变为2.6，从1.8变为0.85。结果表明质子泵的摄取侧与紫色到蓝色的转变之间存在联系。
