3.0 Å RF2 bound 70S Termination Complex

70S Ribosome 3.0A RF2

The PDB file contains the two 70S ribosome copies in the crystallographic asymmetric unit. Each copy includes the 30S and 50S subunits, messenger RNA, P- and E-site tRNA and release factor 2 bound in the A site in response to a UAA stop codon on the mRNA.

The MTZ file contains the structure factor amplitudes against which the model was refined.

3.2 Å RF1 bound 70S Termination Complex

The PDB file contains the two 70S ribosome copies in the crystallographic asymmetric unit. Each copy includes the 30S and 50S subunits, messenger RNA, P- and E-site tRNA and release factor 1 bound in the A site in response to a UAA stop codon on the mRNA.

The MTZ file contains the structure factor amplitudes against which the model was refined.

This PYMOL script provides easy means of inspecting the structure.
