Nucleic acid polymerases have evolved elaborate mechanisms that prevent incorporation of the non-cognate substrates, which are distinguished by both the base and the sugar moieties. While the mechanisms of substrate selection have been studied in single-subunit DNA and RNA polymerases (DNAPs and RNAPs, respectively), the determinants of substrate binding in the multisubunit RNAPs are not yet known. Molecular modeling of Thermus thermophilus RNAP-substrate NTP complex identified a conserved beta… CONTINUE READING
