Abstract

Reproducible results describing the effects of pH on the response of the labellar sugar receptor of the fleshfly, Boettcherisca peregrina, were obtained. The response to sucrose was independent over a wide range of pH (3.0 to 10.0 for sucrose stimulation), but was inhibited fairly sharply on both sides of this range. Similar results were obtained for monosaccharide stimulation. The receptor was excited on stimulation by water above pH 12.0. The effects of high pH, both inhibitory and excitatory, were affected by the presence of salts. In the presence of 0.5 molar NaCl, for example, the pH-inhibition curve was shifted toward lower pH's by about one pH unit. The effects of low pH, on the other hand, were not affected by salts. Following Dixon's theory, it was concluded that at least five ionizable groups (loosing positive charges above pH 10.5) were located at the receptor site.

摘要

获得了关于pH对麻蝇（Boettcherisca peregrina）唇瓣糖受体反应影响的可重复结果。在很宽的pH范围内（蔗糖刺激时为3.0至10.0），对蔗糖的反应是独立的，但在此范围两侧会受到相当明显的抑制。单糖刺激也得到了类似结果。当pH高于12.0时，受体在水刺激下会被激活。高pH的抑制和激活作用都受到盐的影响。例如，在存在0.5摩尔氯化钠的情况下，pH抑制曲线向较低pH方向移动约一个pH单位。另一方面，低pH的影响不受盐的影响。根据狄克逊理论，得出结论：至少有五个可电离基团（在pH高于10.5时失去正电荷）位于受体部位。
