T7 R&DNA™ Polymerases - Mutant T7 RNA Polymerases for synthesis of RNA, DNA, or transcripts of mixed dNMP/rNMP or modified 2'-NMP/rNMP composition

BioSearch Tech (Lucigen/Epicentre)

T7 R&DNA™ Polymerase* is a recombinant mutant form of T7 RNA polymerase (Y639F mutant), in which Tyr-639 has been replaced by Phe.1,2 This mutation enables T7 R&DNA Polymerase to incorporate 2´-deoxyribonucleoside triphosphates (dNTPs) into full-length transcripts much more efficiently than the corresponding wild-type enzyme,1 while retaining the same catalytic activity for incorporation of canonical NTPs, and the same high promoter specificity as wild-type T7 RNA Polymerase. The ability of this mutant enzyme to incorporate certain 2´-modified-dNTPs (including but not limited to dNTPs having a 2´-fluorine or 2´-amino group) enables efficient in vitro synthesis of transcripts composed of mixed rNMP/2´-dNMP or rNMP/2´- modified-dNMP from any DNA template that is downstream of the T7 RNA polymerase promoter. Such modified transcripts are useful for many applications.

Note: Complete substitution of one 2´-dNTP (or one 2´-modified dNTP) for a canonical rNTP in a T7 R&DNA Polymerase reaction results in a slight decrease in yield. Additional substitutions of 2´-dNTPs (or 2´-modified-dNTPs) for canonical rNTPs will further reduce yield of the transcript produced. Substitution with all four 2´-dNTPs (or 2´-modified dNTPs) will result in extremely low yields of transcript and is NOT RECOMMENDED.
