A series of L-histidine Schiff bases that include Sal-His (H2L^1), Br-Sal-His(H2L^2), NO2-Sal-His (H2L^3) and their Cu complexes were synthesized, and the catalytic behavior of Schiff-base-Cu for the oxidation of β-ionone to 4-oxo-β-ionone as well as the effects of substitutents on these properties were examined.

合成了芳环上含不同取代基的Schiff碱配体（水杨醛缩组氨酸(H2L^1)、5-溴水杨醛缩组氨酸(H2L^2)、5-硝基水杨醛缩组氨酸(H2L^3)及其铜配合物，研究了其作为催化剂应用于催化分子氧氧化β-紫罗兰酮制备4-氧代－β-紫罗兰酮中的行为。

To understand the molecular basis of the high selectivity of the inhibitor and the mechanism of feedback inhibition, we determined the crystal structure of LiCMSC (C-terminal regulatory domain of LiCMS) in complex with isoleucine, and performed a biochemical study of the inhibition of LiCMS using mutagenesis and kinetic methods.

丁建平和赵国屏课题组合作，运用结构生物学和生物化学的方法分别研究了 CMS 的催化结构域与其底物丙酮酸、乙酰辅酶 A 、金属辅基的四元复合物的晶体结构，和 CMS 的调节结构域与反馈抑制剂异亮氨酸的复合物的晶体结构，以及全酶与这些配体相互结合的动力学性质。

These results were different from the observation in the reaction of Cp2LnNPr2 and PhEtCCO,indicating that ligand, steric effect, electronic effect and solvents have an important effect on the insertion of a ketene into the Ln-N bond.

与phEtCCO不同的是，phZCCO偶联插入LoN键形成的新配体不发生1，5一H迁移的异构化反应，可以直接分离得到苯环参与共扼加成反应的中间体CpZLn〔oe(e6HSCphCON'p几)CphZLn-Er(11，孔(12)，Y(13)。

The results give evidence about the flexing of the corrin ring and the steric interactions between the corrin ring and the Ado group, which have been suggested to be important in enzyme-induced distortion and lability of the CoC bond.

结果进一步证实咕啉环的扭曲及咕啉环与5＇—脱氧腺苷配体之间的立体相互作用在酶诱导Co—C键均裂过程中的重要作用。
