帮忙翻译一下,实在是看不懂!要是软件翻译的帮忙看看顺不顺,谢谢了!!!!
Eukaryotic peptide elongation occurs in very similar fashion to the process in prokaryotes. An incoming aminoacyl-tRNA enters the ribosomal A site while peptidyl-tRNA occupies the P site. Peptidyl transfer then occurs,followed by translocation of the ribosome one codon further along the mRNA. Two elongation factors,eEF-1 and eEF-2,mediate the elongation steps. eEF-1 consists of two components: eEF-1A and eEF-1B. eEF-1A is the eukaryotic counterpart of EF-Tu; it serves as the aminoacyl-tRNA binding factor and requires GTP. eEF-1B is the eukaryotic equivalent of prokaryotic EF-Ts; it catalyzes the exchange of bound GDP on eEF-1: GDP for GTP so that active eEF-1: GTP can be regenerated. EF-2 is the eukaryotic translocation factor. eEF-2(like its prokaryotic kin, EF-G) binds GTP, and GTP hydrolysis accompanies translocation.

真核生物肽伸长发生在非常类似的方式对这一进程在原核生物。来袭氨酰trna进入核糖体的土地,而肽的trna抢占站点。肽转移,然后发生,其次是易位的核糖体的一个密码子沿着表达。两个伸长因素, eef - 1和eef - 2 ,调解伸长步骤。 eef - 1 ,由两部分组成: eef - 1a和eef - 1b型。 eef - 1a是真核对应的英法图,它充当氨酰trna结合因子,并要求城市规划师。 eef - 1b的,是真核相当于原核英法商贸易,它催化的交流,必将对国内生产总值eef - 1 :国内生产总值为师,使活跃eef - 1 : gtp的,可再生的。英法- 2 ,是真核易位的因素。 eef - 2 (如原核健,英法荷)所约束的城市规划师,城市规划师水解伴随易位。
真核肽链终止要求只有一个释放因子
而原核生物终止涉及三个不同释放因子( rfs ) ,只有一个射频足以真核生物终止。真核射频结合的核糖体的地点是gtp的依赖性和射频:岛屿总产值绑定在这个站点时,它是被终止密码子。然后,水解的肽基的trna酯键,水解的城市规划师,释放新生肽和deacylated的trna ,核糖体解离,从基因接踵而至。
抑制蛋白质合成
蛋白质合成抑制剂已送达两个大,或许是互补的,目的。首先,他们都非常有用科学方法,在阐明生化机制的蛋白质合成。第二,有些这些抑制剂的影响原核,而不是真核细胞的蛋白质合成,因此是医学上的重要抗生素。表30.10是一个局部的名单,这些抑制剂和方式采取行动。结构部分这类化合物是由于在图30.30 。
