The susceptibilities of the 3th instar larvae of Spodoptera litura fed on diets treated with nicotine and rutin to AucaNPV, fipronil and spinosad were studied. The activities of CarE and GSTs in different treated cutworms were also tested. The results showed that the nicotine enhanced significantly the susceptibility of Spodoptera litura to insecticides, and the susceptibility enhanced as the nicotine concentration in the diets increased.

以在人工饲料中添加植物次生物质的方法，研究了取食不同含量烟碱、芸香苷的斜纹夜蛾Spodoptera litura 3龄幼虫对银纹夜蛾核多角体病毒、氟虫腈及多杀菌素的敏感性，同时测定了各处理组幼虫体内羧酸酯酶和谷胱甘肽转移酶的活性。

This work made preparations for the further in-vitro study on the activity of glycosyltransferase and the usage of different glucosyl.Several important factors for protoplast preparation from Amycolatopsis-orientalis were studied and optimized such as the type of substrate, the concentrations of the addition of glycin, the concentrations of lysozyme and so on.

并且通过酸水解的方法获得了脱去一个糖基的万古霉素假糖苷，可以将其作为酶转化反应的底物，为进一步在宿主菌体外研究糖基转移酶的活性以及不同糖基的生理作用做好准备。

Neutral proteinase was used to hydrolyse Acetes chinensis protein to prepare active peptides, which could inhibit the activity of angiotensin I-converting enzyme.

采用3942中性蛋白酶酶解中国毛虾蛋白，制备具有抑制血管紧张素转移酶活性的多肽。

Moreover, MeJA induced defense genes, such as pathogenesis-related proteins (PR2a), phenylalanine ammonia-lyase, BX9, and TPS. MeJA also increased DIMBOA and Vannillic acid content of leaves and roots significantly but leaf p－Hydroxybenzoic acid concentration was decreased significantly and Protocatechuric acid was produced in roots only.

1MeJA叶片处理能诱导叶片和根系中丙二烯氧化物环化酶基因、糖基转移酶（BX9）基因、苯丙氨酸转氨酶基因的表达，使叶片和根系中丁布含量升高，同时，6μL/L MeJA处理使第二叶中原儿茶酸含量显著降低，诱导根中产生原儿茶酸，使第二叶中香草酸含量和根中未知物质峰面积显著增大。

Bacterial enolpyruvyl transferase is one of the key enzymes acting in the initial stage of peptidoglycan synthesis of bacterial cell walls.

肽聚糖是细菌细胞壁的重要成分，烯醇式丙酮酸转移酶是调节肽聚糖合成初始阶段的关键酶。

Telomerases are very interesting DNA polymerases in that they carry an RNA template for the telomere sequence within them.

端粒末端转移酶是一种非常有趣的DNA多聚酶，它们带有决定端粒序列的RNA模板。
