==About this Structure==
</table>
[[1msw]] is a 4 chain structure with sequence from [http://en.wikipedia.org/wiki/Enterobacteria_phage_t7 Enterobacteria phage t7]. The April 2003 RCSB PDB [http://pdb.rcsb.org/pdb/static.do?p=education_discussion/molecule_of_the_month/index.html Molecule of the Month] feature on ''RNA Polymerase''  by David S. Goodsell is [http://dx.doi.org/10.2210/rcsb_pdb/mom_2003_4 10.2210/rcsb_pdb/mom_2003_4]. Full crystallographic information is available from [http://oca.weizmann.ac.il/oca-bin/ocashort?id=1MSW OCA].  
== Function ==
[https://www.uniprot.org/uniprot/RPOL_BPT7 RPOL_BPT7] DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Responsible for the transcription of the late genes of T7. It is rifampicin-resistant. It recognizes a specific promoter sequence, unwinds the double-stranded RNA to expose the coding strand for templating, initiates transcription preferentially with a purine.
