WebJul 29, 2024 · Transcription initiation is a key checkpoint and highly regulated step of gene expression. The sigma (σ) subunit of RNA polymerase (RNAP) controls all transcription initiation steps, from recognition of the −10/−35 promoter elements, upon formation of the closed promoter complex (RPc), to stabilization of the open promoter complex (RPo) and … WebThe genome of the extremely thermophilic T. thermophilus phage P23–45 does not possess RNAP coding sequences. The host RNAP cannot identify the conserved 11-bp motif in the early gene promoters. Nevertheless, host RNAP in combination with phage gp76 and gp39 proteins regulate the transcription of middle and late genes.
