Function[RPOB_MYCTU] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.[HAMAP-Rule:MF_01321] Publication Abstract from PubMedCarD from Mycobacterium tuberculosis (Mtb) is an essential protein shown to be involved in stringent response through downregulation of rRNA and ribosomal protein genes. CarD interacts with the beta-subunit of RNAP and this interaction is vital for Mtb's survival during the persistent infection state. We have determined the crystal structure of CarD in complex with the RNAP beta-subunit beta1 and beta2 domains at 2.1 A resolution. The structure reveals the molecular basis of CarD/RNAP interaction, providing a basis to further our understanding of RNAP regulation by CarD. The structural fold of the CarD N-terminal domain is conserved in RNAP interacting proteins such as TRCF-RID and CdnL, and displays similar interactions to the predicted homology model based on the TRCF/RNAP beta1 structure. Interestingly, the structure of the C-terminal domain, which is required for complete CarD function in vivo, represents a distinct DNA-binding fold. Structure of the Mtb CarD/RNAP beta-Lobes Complex Reveals the Molecular Basis of Interaction and Presents a Distinct DNA-Binding Domain for Mtb CarD.,Gulten G, Sacchettini JC Structure. 2013 Sep 17. pii: S0969-2126(13)00306-7. doi:, 10.1016/j.str.2013.08.014.
