青酶

A phenylalanine ammonia-lyase gene was clone from Nerium oleander for the first time and it was also the first cloned gene involved in anthocyanin metabolic pathway in N.oleander.

首次从夹竹桃中克隆得到苯丙氨酸解氨酶基因cDNA片段，并命名为NoPAL1，GenBank登录号为AY747677，这也是首次从夹竹桃花青苷代谢途径中克隆得到的基因。

The level of serum uric acid and urinary uric acid were determined by phosphotungstic acid method.

目的 观察青秦液对高尿酸血症大鼠尿酸代谢及相关酶活性的影响。

Methods Forty-eight healthy black and blue rabbits were chosen and divided into 6 groups at randomly. Experimental groups were performed surgery with CO2 laser sclerectomy in both eyes. Contents of nitric oxide and malonyldialohyed and the activity of Na(superscript +)-K(superscript +)-ATPase were tested with biochemical assays.

健康青紫兰兔48只，随机分为6组，实验组动物双眼均接受CO2激光外路巩膜切除术，化学比色法测定视网膜匀浆中一氧化氮、丙二醛的含量和Na-K-ATP酶的活性，进行统计学分析。

Trichloroacetic acid is a kind of short-stopper which can stop enzymatic reaction.

三氯乙酸是澳洲青苹PPO酶促反应有效的终止剂。

Objective To modify the synthesis of Benzhydryl 2α- methyl - 2β- [ ( 1,2,3 -triazol - 1 - yl)- methyl ] penicillanate - 1,1 - dioxide, the key intermediate of β- lactamase in-hibitor tazobactam.

目的 改进β-内酰胺酶抑制剂泰唑巴坦关键中间体2α-甲基-2β[(1，2，3-三唑-1-基)-甲基]青霉烷酸砜二苯甲酯的合成。

Above all, the key index of colouration mechanism of'Ralls'and bud mutation is anthocyanin content and CHI activity.Key words apple; bud mutation; coloring mechanism; bagging

综上结果，芽变与原有品种在着色机理上的关键指标是果皮花青苷含量和CHI酶活性。

The 329 bp terminal inverted repeat sequence can't form the conserved fold-back secondary structure as that of many Streptomyces linear replicons. Lacking of typical Streptomyces tap/tpg locus for te-lomere replication, pPR2.3c encodes a protein with two domains resembling the telomere associated protein of Strepto-myces and helicase of Haemophilus respectively. No typical Streptomyces iteron-rep locus for replication from the cen-trally located origin, two DNA fragments containing almost all pPR2 were cloned and introduced by transformation into S.

其端粒末端反向重复序列的长度为329 bp，不能像多数链霉菌的线型质粒那样能形成保守的&折返&的二级结构。pPR2虽然没有参与链霉菌端粒复制的保守的tap/tpg基因，但是pPR2.3c基因编码了一个双结构域蛋白，分别同链霉菌的端粒复制相关蛋白Tap和嗜血杆菌的解旋酶具有相似性。pPR2缺少典型的链霉菌重复序列-复制基因区段，将几乎覆盖全长pPR2的两段DNA进行克隆后，不能转化变铅青链霉菌。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
