Abstract
On the basis of coincidence of all activation parameters (E, deltaH*, deltaF* and deltaS*) for the reaction of cleavage of cytidine-2';3'-monophosphate catalyzed by "acid" (pH-optimum 4.7) nonspecific RNAses from Aspergillus clavatus and Penicillium brevicompactum (EC 3. 1. 4. 23) it has been proposed that the mechanism of action on this reaction stage (hydrolysis) for both enzymes is equal.
摘要
基于来自棒曲霉和短密青霉的“酸性”（最适pH 4.7）非特异性核糖核酸酶（EC 3.1.4.23）催化胞苷-2′；3′-单磷酸裂解反应的所有活化参数（E、ΔH*、ΔF和ΔS）均相符，有人提出这两种酶在该反应阶段（水解）的作用机制是相同的。
