The TFIIB linker domain stimulates the catalytic activity of archaeal RNAP. By characterising a range of super-stimulating mutants we identified a novel rate-limiting step in transcription initiation. Our results help to interpret structural findings and pave the way towards higher-resolution structures of the RNAP-TFIIB linker interface.
TFIIB连接域可刺激古细菌RNA聚合酶的催化活性。通过对一系列超刺激突变体进行表征,我们在转录起始过程中确定了一个新的限速步骤。我们的结果有助于解释结构研究结果,并为解析RNA聚合酶-TFIIB连接界面的高分辨率结构铺平道路。
