The three-dimensional structure of the N-terminal domain of an archaeal TFIIB, which has high sequence homology with eucaryal analogues, is strikingly similar to that of the C-terminal zinc ribbon of the eucaryal transcription elongation factor TFIIB.
古细菌TFIIB的N端结构域的三维结构与真核生物类似物具有高度的序列同源性,与真核生物转录延伸因子TFIIB的C端锌带结构惊人地相似。
