核糖体

At the moment, a number of relevant genes in the bacteroid related to the symbiosis were activated, and the expressed quantity of protein remarkably increased.

为了探明这种改变是否与合成蛋白质的细胞器一核糖体有关，比较分析了苜蓿根瘤菌在自生和共生状态下核糖体蛋白的表达谱。

Circularization may facilitate recycling of translation factors and/or the ribosome, since ribosomes leaving the 3'end of the mRNA would be in close proximity to the 5'end for reinitiation.

环化可能有利于翻译因子和/或核糖体的循环利用，当核糖体从3'端离开后就处于5'端附近。

The result showed that twocDNA fragments which expressed at high level both in shoot and radicle representedthe gene encoding beta-D-glucosidase; one cDNA fragment expressed specifically inshoot represented the gene encoding mitochondria HSP60; most clones of MF12 andMF17 fragments respectively represented the chloroplast genes encoding prp22 andprp19 proteins which are two components of ribosomal small subunit; while thededuced amino acid sequence from each exceptional one clone was respectivelyhomologous to CDC5 proteins and vesicle-associated membrane proteins; otherthree cDNA fragments expressed preferentially in shoot had no homologue inGenBank.

结果发现2个在胚芽和胚根中表达量都很高的cDNA片段代表的是编码玉米β-D-葡糖苷酶的基因；一个在胚芽中表达而在胚根中不表达的片段代表的是编码线粒体分子伴侣HSP60的基因；片段MFl2的大部分克隆测序结果是与叶绿体基因组中编码核糖体小亚基蛋白prp22的基因同源，但其中有一个克隆测定的cDNA片段序列推测的氨基酸序列与CDC5家族成员有较高的同源性；片段MF17的大部分克隆测序结果与叶绿体基因组中编码核糖体蛋白prp19的基因同源，而有一克隆测定的cDNA片段序列推测的氨基酸序列与参与信号转导的膜结合蛋白VAP27和VAMP有较高的同源性；另有3个优先在胚芽中表达的cDNA片段未查询到同源序列。

At first, RIP is isolated from seeds of bitter melon. The result of SDS-PAGE indicates that there are lots of R*IP in the abstraction liquid.

核糖体灭活蛋白是一类广泛存在于高等植物细胞内的能抑制核糖体功能的植物蛋白。

RPLP0 gene encodes the acidic ribosomal phosphoprotein large PO subunit, which is a component of the 60S subunit.

RPLP0基因编码酸性核糖体磷蛋白大亚基P0，是核糖体60S亚基的组成成分之一。

"Our next goal is to trap the ribosome in other functional states to get more frames of the movie," he said.

他说，"我们下一步目标就是跟踪核糖体的其它功能，以制作出更为详细的核糖体分子结构图"。

The results showed that Me-c84 shared 98% similarities with the 26S ribosomal RNA gene from Sarracenia purpurea, while M14-86 shared97% similarities with the 26S ribosomal RNA gene from Portulaca Grandiflora.

将已经获得的两条cDNA序列与NCBI网站上的GenBank数据库进行同源序列比对，结果显示Me-c84核苷酸序列与瓶子草等植物的26S核糖体RNA部分基因同源性达到98％。M14-86核苷酸序列与大花马齿苋等植物的26S核糖体RNA部分基因同源性达到97％。

The whole sequence of LSU rDNA from Umbilicaria esculenta was made by Wei's lab., and the other whole sequences of LSU rDNA from 18 species were obtained from GenBank.

用于研究的美味石耳的核糖体核酸基因大亚基全序列是由本实验室所提供；其他18种核糖体核酸基因大亚基全序列来自GenBank。

The thiopeptides, by binding within a cleft located between the ribosomal protein L11 and helices 43 and 44 of the 23S rRNA, overlap with the position of domain V of EF-G, thus explaining how this class of drugs perturbs translation factor binding to the ribosome.

核糖体蛋白L11和23SrRNA的43/44螺旋结构形成裂隙，L11的构象变化能够加宽该裂隙从而允许延伸因子EF-G插入，促使GTP水解，为肽链延伸合成过程中核糖体的构象变化提供能量，而Thio能够与L11和23sRNA结合，阻止L11的构象变化，使该裂隙处于闭合状态，抑制EF－G在延伸过程中的作用。

A cluster of ribosomes connected by a strand of messenger RNA and functioning as a unit in protein synthesis.
