User:Karsten Theis/T7RNAP physical model explanation
From Proteopedia
This is a tour of a physical model of the T7 virus RNA polymerase (PDB ID 1msw).
Above is a photograph of the two parts of the model. To assemble it, you bring the two flat sides together (the view is a "butterflied" version of the structure). On the left is the N-terminal part (roughly) with the nucleic acid forming a transcription bubble. On the right is the C-terminal part (roughly), in the shape of the right hand, with the active site at the palm. For an annotated image, see below.
