肽酶

Extra-cytoplasmic polypeptides are usually synthesized as 'preproteins' carrying amino-terminal, cleavable signal peptides and secreted across membranes by translocases.

中文摘要：细胞外多肽一般是被合成为含有在多肽链末端可被切除的信号肽的&前体蛋白&，再通过转移酶跨膜分泌出去。

The results showed that(1) UV-B irradiation can inhibit the growth and photosynthetic rate of Nitzschia closterium,and the inhibiting effects were more significant when the time was prolonged;(2) UV-B irradiation decreased soluble sugar.In the initial 2 days,soluble sugar of N.closterium decreased rapidly,the soluble sugar on the 4~ day has...

结果表明：(1)随着UV-B暴露时间的延长，UV-B辐射对藻的生长以及光合速率有抑制作用，并且时间越长，抑制作用越明显；(2)UV-B辐射使小新月菱形藻可溶性糖含量降低，而且在最初的2d，UV-B辐射使可溶性糖含量降低迅速，第4天的可溶性糖含量稍有所升高但与第2天相比差异不显著，UV-B辐射第6天，可溶性糖含量又迅速降低；(3)UV-B辐射的可溶性蛋白含量在第2天明显升高，随后又快速下降；(4)对照组的还原型谷胱甘肽含量的变化随时间延长而升高，UV-B辐射第2天的GSH含量比初始状态(0d)的GSH含量稍有升高，但变化不明显，第2天之后，GSH含量随时间延长而快速降低；(5)对照组的过氧化物酶活性随时间延长而升高，UV-B辐射第2天的POD活性比初始状态(0d)的POD活性显著升高，第2天之后，POD活性随时间延长而快速降低。

The efficacy of this technique for protein mapping was demonstrated by the mass spectral analyses of the peptide fragmentation of several proteins, including lysozyme, albumin, conalbumin, and ribonuclease A.

我们利用四种蛋白质，溶菌蛋白、白蛋白、伴蛋白和核醣核酸酶A的胜肽片段之质谱分析而证明这个方法是非常有效率的。

Endolysin is the enzyme encoded by bacteriophage and directly targets bonds in the peptidoglycan layer of the bacterial cell wall. The result of this activity is degradation of the rigid murein layer and release of newly assembled virions at the terminal stage of the phage reproduction cycle.

溶菌酶为噬菌体进行溶菌期所需之酵素，其能作用在细菌之肽聚醣而使细菌之细胞壁分解，以利组装好的噬菌体释出。

In this study, an attempt is made to account for the observed difference in the susceptibility of Gossypium hirsutum L.(cv. BD-18 and Simian 3, resistant and susceptible to V. dahliae, respectively) to toxin of Verticillium dahliae, by looking for differences in the timing and level of production of NO and H_2O_2, and their effects on the expression of GST gene.
