Abstract
- A further fraction of ;cell-bound exopenicillinase', in addition to that bound ionically to the surface of the cell wall, has been identified in Staphylococcus aureus. 2. Treatment of cells with low concentrations (0.01m) of organic anions liberates part of this exopenicillinase, such liberation being dependent on both time and temperature, but independent of an external supply of energy. 3. Tricarboxylic acids tend to be more effective than dicarboxylic or monocarboxylic, although there are large differences between ionic species even when tested at the same normalities.
摘要
金黄色葡萄球菌中还存在另外一部分“胞壁结合型青霉素外切酶”，这种酶除了与细胞壁表面呈离子键结合外，还有一部分与细胞壁结合。
用低浓度（0.01m）的有机阴离子处理细胞，可以释放部分这种青霉素外切酶，这种释放既依赖于时间又依赖于温度，但不依赖于外部能量供应。
三羧酸往往比二羧酸或一羧酸更有效，尽管即使在相同的离子强度下测试，不同的离子种类之间也存在很大差异。
