多肽链延伸因子
多肽链延伸因子
多肽链延伸因子 polypeptide chain elonga-tion factor蛋白质生物合成中参与多肽链延伸过程的蛋白质因子。从大肠杆菌等原核细胞可纯化获得三种延伸因子(elongation factor),即eftu,efts和efg,分子量大约分别为4.7万,3.6万和8.3万。eftu与gtp结合成eftu-gtp,然后再与氨酰trna结合,形成三复合体(ternary complex)氨酰-trna-eftu-gtp。这种三复合体与核糖体的氨酰trna部位(a部位,aminoacyl site)结合,继而gtp被分解,eftu以eftu-gtp的形式从核糖体上游离出来。游离的eftu-gdp与efts反应,再生成eftu-ts,然后与gtp结合成eftu-gtp。另一方面结合在p部位(peptide transfer)。多肽链即可延长一个氨基酸残基。接着肽基trna从a部位转移(translccation)到p部位,p部位的trna从核糖体上脱离下来。该反应由efg(g因子,亦称为移位酶)催化,再将一分子的gtp水解。如图所示,由于上述反应的逐次反复进行,而使多肽链延伸反应得以进行,每延长一个氨基酸残基,就水解两分子gtp。动物细胞或其他真核细胞基本上也以同样机制进行多肽链的延伸,并且也分离到了对应于原核细胞的各因子。
