Figure 2: Homology model of Tet(O).
From: Mechanism of tetracycline resistance by ribosomal protection protein Tet(O)
(a) The initial Tet(O) model (red) and the EF-G structure (green, PDB code: 2WRI) are shown as overlaid ribbons in the segmented density map (red mesh). The three loops in domain IV are seen to be positioned differently in the two structures. (b) The map-fitted structure of Tet(O) (red) is superimposed with the crystal structure of EF-G, showing the adjustment in the orientations of the three loops of Tet(O) into the density through the map fitting process.
