Isolation, purification and characteristics of D-hydantoinase were carried out. The experiment results showed that the optimal pH and temperature of pure D-hydantoinase were pH 8. 5 and 35℃, respectively. D-hydantoinase activity could be increased significantly by Mn〓 and Fe〓. Substrate specificity of D-hydantoinase on various hydantoin derivatives showed the optimal substrate of D-hydantoinase was 5-phenylhydantoin, but hydantoin, 5-methylthioehylhydantoin, 5-hydroxyphenylhydantoin, 5-methylhydantoin, 5-benzylhydantoin could also be hydrolyzed by D-hydantoinase.

本文还进行了海因酶的分离纯化及性质研究，发现酶的最适反应温度为35℃，最适pH为8.5，金属离子Mn〓和Fe〓能显著提高D-海因酶活力。D-海因酶的特异性实验表明，D-海因酶的最适底物为D，L-苯海因，其次为海因，D，L-对羟基苯海因和D，L-甲硫乙基海因，对D，L-甲基海因和D，L-苯甲基海因也有一定的作用。

Study on kinetics of chromium reduction by hydrazine in the alkaline solution

性质：有机化合物分子在还原剂作用下发生的偶联反应。

Hydrocyanic acid and water proceed via a five-centred transition states then transformed by its exterior hydrogen-bond; The results show that the activation energy of the isomerizing reaction in the aqueous phase is lower than that in the gas phase. It is likely that the hydrogen bonds formed in the complexes and the solvent effect play an important role.

计算结果表明，在水相中异构化过程的活化能比在气相中低，无论在气相还是在水相中异氢氰酸通过水氢键转化成氢氰酸容易些，而氢氰酸由水氢键转化成异氢氰酸相对要困难些，分子间氢键和溶剂化效应在异构化反应过程中起到重要的作用。
