Fig. 5: Crystal structure of full-length FasR in complex with DNA.

Electron density map (sigmaA-weighted 2mFobs-DFcalc Fourier) is shown (magenta mesh), overlaid on the final refined model, showing the protein dimer (protomers in light blue and pale green) and the DNA double helix (orange) in cartoon representation. The map was carved around the atomic model with a border of 3 Å to improve the clarity. Helices α3 are seen fitting within the DNA major groove as expected.
