- Based on density-functional theory (DFT) and density-functional perturbation theory (DFPT) we have discussed systematically the hydrogen isotope effects on the thermodynamic properties of TiX2 (X=H, D, and T) system. 应用基于密度泛函理论(DFT)和密度泛函微扰理论(DFPT)的 PWSCF和PHONONS第一原理计算程序系统研究了TiX2(X=H,D,T)系统热力学特性的同位素效应。
- The decreased activity by 50 fold and the kinetic isotope effects show that CH1 bond cleavage is more rate-limited in the Y429F mutant, consistent with the proposed proton shuttling by Tyr429. 其中Y429F突变株酵素活性下降约50倍，且从其动力学同位素效应结果显示，Y429的突变使CH1键结断裂的速率更受到限制，乃符合Y429作为活性中心碱基之推测。
