RNA polymerases catalyse the DNA dependent polymerisation of RNA. Prokaryotes contain a single RNA polymerase compared to three in eukaryotes (not including mitochondrial. and chloroplast polymerases). Rpb2 is the second largest subunit of the RNA polymerase. This domain forms one of the two distinctive lobes of the Rpb2 structure. This domain is also known as the lobe domain [1]. DNA has been demonstrated to bind to the concave surface of the lobe domain, and plays a role in maintaining the transcription bubble [1]. Many of the bacterial members contain large insertions within this domain, as region known as dispensable region 1 (DRI).
This is the RNA polymerase interacting domain (RID) of transcription-repair-coupling factor (TRCF), CarD and CarD homologue in Myxococcus xanthus, called CdnL. In Myxococcus xanthus, CdnL is a protein required for the activation of light- and starvat ...
This is the RNA polymerase interacting domain (RID) of transcription-repair-coupling factor (TRCF), CarD and CarD homologue in Myxococcus xanthus, called CdnL. In Myxococcus xanthus, CdnL is a protein required for the activation of light- and starvation-inducible genes [1]. It interacts with the zinc-binding protein CarG to form a complex that regulates multiple processes in Myxococcus xanthus [4]. CarD is widely distributed among bacteria and represents a distinct class of RNAP binding proteins that regulate transcription and essential processes [4-8]. TRCF displaces RNA polymerase stalled at a lesion, binds to the damage recognition protein UvrA, and increases the template strand repair rate during transcription [3].
This entry represents the C-terminal helical domain of CarD from Mycobacterium tuberculosis, a RNAP-binding protein that regulates transcription and essential processes [1-3]. This domain binds DNA in a non-specific manner [4].
