Catalytic triad

The role played by elements of the 《 catalytic triad 》 in increasing the reactivity of serine hydroxyl has been discussed .

讨论了催化三联体各组份对增加丝氨酸羟基反应能力所起的作用。

As the members of the serine protease family , acetylcholinesterase , α - chymotrypsin and subtilisin had the similar structural character in active sites . All of them had the catalytic triad composed of serine , histidine and asparagine ( or glutamic acid ) .

丝氨酸蛋白水解酶家族成员乙酰胆碱酯酶、α-糜蛋白酶、枯草杆菌蛋白酶的催化中心具有相似的结构特征，即由丝氨酸、组氨酸、天冬氨酸（谷氨酸）组成的催化三联体。

In addition , there has still been a hot debate on the existence and significance of low-barrier H-bond ( LBHB ) in catalytic triad of serine proteases .

此外，低垒氢键在酶催化中的存在性及其意义也是人们目前争论的焦点问题之一。
