2) selenocysteine insertion sequence(SECIS)
硒代半胱氨酸插入元件(SECIS)
3) SECIS
硒代半胱氨酸插入元件
1.
UGA codon is a stop signal codon normally in the process of protein synthesized but a Sec codon when there is a selenocysteine insertion sequence(SECIS) in the 3 -untranslater region of mRNA sequence.
UGA密码子通常作为蛋白质合成的终止密码子,当mRNA链的3’-非翻译区(3’-UTR)出现硒代半胱氨酸插入元件(SECIS)时,UGA密码子就成为硒代半胱氨酸(Sec)的插入码。
2.
In this paper, we introduce the structural characteres of the selenocysteine insertion sequences (SECIS), the bioinformatics methods of searching selenoprotein from genome and its research progress.
本文依据硒代半胱氨酸插入元件(SECIS)结构特征、利用从基因组中寻找硒蛋白的生物信息学方法对大鼠基因组进行了搜索,并将结果与目前已知的硒蛋白基因进行了比对,从而证实了本文工作的合理性。
4) selenocysteine
硒代半胱氨酸
1.
The discovery of codon character of selenocysteine as the 21st natural amino acid and the identification of new selenoproteins based on the character of SECIS by bioinformatics are also reviewed.
硒是人体必需的微量元素,以硒代半胱氨酸(Sec)的形式存在于蛋白质中作为硒酶的活性中心发挥作用,其生物功能主要是抗氧化。
2.
As the twenty first amino acid, selenocysteine can be co translationally incorporated into the polypeptide chain at UGA codon in the coding region of selenoprotein mRNA.
作为第 2 1种氨基酸 ,硒代半胱氨酸在翻译阶段由核糖体介导 ,在mRNA编码区的UGA密码子处参入多肽链。
3.
In selenoproteins, Se is incorporated into proteins in the form of selenocysteine (Sec), the 21st amino acid.
硒在蛋白中以第21种氨基酸――硒代半胱氨酸(Sec)的形式存在。
5) selenocystein
硒代半胱氨酸
1.
The sequence of the cloned cDNA contains 10 UGA codon in the open reading frame of mRNA Selenocysteine is incorporrated into the primary structure of the protein at a UGA codon .
硒蛋白P(SeP)是从大鼠和人血浆中分离、纯化得到的一种糖蛋白 ,每个硒蛋白P多肽含有10个硒代半胱氨酸。
2.
Since selenocystein, the active center of the selenoprotein, is translated in response to UGA codon (a stop signal in the canonical genetic code), selenoproteins are misannotated or completely lost by general program.
然而,由于硒蛋白的活性中心硒代半胱氨酸是由传统终止密码子TGA编码,通用的基因分析软件对硒蛋白的注释均产生错误和遗漏,因此需要重新进行硒蛋白的分析和预测。
