The hydrolysis of ethyl 3,4,6-tri-O-acetyl-2-deoxy-2-amino-β-D-glucopyranoside and acylated-α-chymotrypsins has been investigated. Both transformations are catalyzed by neighbouring nitrogen atom participation. The stereospecificity of acylated enzyme hydrolysis can be explained by the specific steric hindrance of nitrogen participation.
研究了乙基3,4,6-三-O-乙酰基-2-脱氧-2-氨基-β-D-吡喃葡萄糖苷和酰化-α-胰凝乳蛋白酶的水解。两种转化都由邻近的氮原子参与催化。酰化酶水解的立体特异性可以通过氮参与的特定空间位阻来解释。
