During transcription, RNA polymerase moves downstream along the DNA template and maintains a transcription bubble. Several recent structural studies of transcription complexes with a complete transcription bubble provide new insights into how RNAP couples the nucleotide addition reaction to its directional movement.
在转录过程中,RNA聚合酶沿着DNA模板向下游移动,并维持一个转录泡。最近对具有完整转录泡的转录复合物进行的几项结构研究,为RNA聚合酶如何将核苷酸添加反应与其定向移动耦合提供了新的见解。
