A norbornane type ester hydrolase that enantio-selectively hydrolyzes a (.+-.) -exo-norbornane type ester represented by Formula I is provided: ##STR1## wherein R is acyl, and A and B are hydrogens, respectively, or where A and B are absent, resulting in a carbon-carbon double bond between the carbons to which A and B are attached in Formula I. The norbornane type ester hydrolase has an optimal pH of approximately 8 and a stable pH range of approximately 6 to 8.
提供了一种诺博南酯
水解酶,该酶对式I所代表的(.+-.)-外环诺博南型酯具有对映选择性
水解作用:##STR1## 其中R为酰基,A和B分别为氢,或者A和B不存在,在式I中A和B连接的碳之间存在碳-碳双键。该诺博南酯
水解酶的最适pH约为8,稳定的pH范围约为6至8。
