Transcription factors TBP and TF(II)B assemble with RNA polymerase at the promoter DNA forming the initiation complex. Despite a high degree of conservation, the molecular binding mechanisms of archaeal and eukaryotic TBP and TF(II)B differ significantly. Based on recent biophysical data, we speculate how the mechanisms co-evolved with transcription regulation and TBP multiplicity.
转录因子TBP和TF(II)B与RNA聚合酶在启动子DNA处组装,形成起始复合物。尽管具有高度保守性,但古细菌和真核生物的TBP和TF(II)B的分子结合机制存在显著差异。基于最近的生物物理数据,我们推测了这些机制是如何与转录调控和TBP多样性共同进化的。
