sulfhydryl group meaning in Chinese

硫氢基；硫基

The purified enzyme was a monomeric protein whose optimum ph was 8 . 0 . inhibitor study demonstrated that it was a metalloprotease and contained sulfhydryl groups essential for catalytic activity . its activity was inhibited by divalent cations such as zn2 + , mn2 + , and the kj values of zn2 + , mn2 + were imm
这种酶温度适应范围较广，在较大温度变化区间内都具有明显的活性，但是对缓冲溶液ph值的变化却很敏感，体外以明胶为底物时最适温度为38oc ，最适ph值为8
Cml ' s pi is 5 . 7 . the purified cml modified by n - ethymaleimide in the physiological saline containing 8mol / l urea or not did n ' t lose its agglutinate activity . about 3 . 1 sulfhydryl groups in cml were modified in 8mol / l urea and 3 . 2 sulfhydryl groups in cml were modified in the physiological saline without urea
在含8mol l脲和不含脲的缓冲体系中，用n -乙基顺丁烯二酰亚胺( nem )修饰cml的巯基，计算每个cml分子中被修饰的巯基数目分别为3 . 1和3 . 2个，修饰后cml的凝血活性无明显变化。
