2.7.7.6 additional information RNAP mutants: the N-terminal region of T7 RNAP contains a nascent RNA binding site that functions to retain the nascent chain within the ternary complex. The region surrounding residue 240 is involved in binding the initiating NTP. Residues at the very C terminus of T7 RNAP are involved in binding the elongating NTP Escherichia phage T7
