T7 rnap potassium
T7 polymerase is a representative member of the single-subunit DNA-dependent RNAP (ssRNAP) family. Other members include phage T3 and SP6 RNA polymerases, the mitochondrial RNA polymerase (POLRMT), and the chloroplastic ssRNAP. The ssRNAP family is structurally and evolutionarily distinct from the multi-subunit family of RNA polymerases (including bacterial and eukaryotic sub-families). In contrast to bacterial RNA polymerases, T7 polymerase is not in… WebT7 RNA Polymerase. T7 RNAP is a single subunit enzyme of 98 000 Da. It recognizes a 19 bp sequence (consensus: TAATACGACTCACTATAGG) centered on position −8 from …
