查询词典 amino-group

The hydantoin convert enzyme used in this essay is D2 hydantoinase, which has very high convert activity for D2 hydantoin. Therefore, if the used process of conversion do not occur the enzyme, the racemizatoin of hydantoin will be a speed limited step for the process that hydantoinase produce optical active amino acid.

本文采用的海因转化酶系中所含为 D2海因酶，对D2海因的转化活性非常高，由此可见，如若采用的转化体系中没有消旋酶的存在，则海因的消旋成为海因酶转化生产光学活性氨基酸的一个限速步骤。

A new compound, 4-bis (2-chloroethyl) amino-benzoyl picolinoyl hydrazide was synthesized through eight-step reactions.

参照文献方法，以苯胺为原料，经八步合成，制备了新化合物苯甲酰氮芥菸酰肼，并对其结构加以表征。

The trials were carried out in field experiment and artificial climate incubator. The sugar beet growth buds were treated at 1～3pairs of true leaves with gibberellin , autix , naphthaleneacetic acid and kinetin , and the plant growth regulating substances enhancing bolting of sugar beet in the first year and its doses were selected out. The sugar beet seedling induced by temperature and light were treated by abscisic acid , maleic hydrazide , uniconazole (S-3307) and paclobutrazol (PP333), and the plant growth regulating substances which make bolting reverse and their doses were screen out. The mechanisms of bolting and bolting reversing were discussed by examining the changes of endogenous hormones, activities of correlative enzyme to bolting, soluble protein, components of amino acid in the protein, components of fatty acid. The results were as follow

本研究通过田间试验和人工气候箱培养相结合的方法，在甜菜幼苗1~3对真叶时利用赤霉素、生长素、奈乙酸和激动素等生长调节物质处理茎生长点，筛选促进甜菜当年抽苔的植物生长物质及剂量；同时利用脱落酸、马来酰肼、烯效唑（S-3307）和多效唑（PP333）等处理经温光诱导当年抽苔的甜菜幼苗，筛选对当年抽苔逆转有效的种类和剂量，并通过测定内源激素含量、相关酶活性、可溶性蛋白质含量和氨基酸组分及脂肪酸含量及其组分的变化，探讨甜菜当年抽苔和抽苔逆转的机理，得到如下结论

Anti-histidine-tag antibody is usually used for identification of expression of the recombinant protein expressed using pRSET-A. A pair of primers that contained flanking hydropathic amino acid codons were synthesized, to amply the sequence coding for 10~34 aa in the precursor sequence.

质粒pRSET-A是一个常用的高效原核表达载体，编码一N端含组氨酸标签（6×His）的34aa前导肽序列，以方便利用抗组氨酸标签抗体鉴定或纯化所表达的重组蛋白。

A pair of primers that contained flanking hydropathic amino acid codons were synthesized, to amply the sequence coding for 10~34 aa in the precursor sequence. The amplified fragment was inserted into pRSET-A to generate the first double repeat of the precursor gene. By utilizing a pair of isocaudamer BamH I and Bgl II sites, and another downstream Hind III site of plasmid pRSET-A, following a series of simple double digestions and ligation of the resulted products, a series of repeat (3, 4 and 6) precursor peptide fragment genes were derived.

本实验设计一对两侧含编码疏水性氨基酸密码子的引物，经过扩增前导序列10~34aa基因序列，并重新克隆入质粒pRSET-A构建串联二聚体后，再利用质粒pRSET-A的BamH I / Bgl II同尾酶克隆位点，经一系列简单的酶切和连接，快速构建这一前导肽中不含组氨酸标签序列的串联多聚体基因，并成功表达其六聚体重组蛋白。

Active Ingredient 】 Hydroxy lichen amino acid, Extractant from plants, and Potentiating agent.
