Assessment of NorA efflux pump structure.

Notes: (A) Ramachandran plot calculations of three-dimensional (3D) model computed using PROCHECK. (B) Compatibility of atomic 3D model of its own amino acid residues (1D) using Verify3D server. (C) 3D profiles of constructed 3D model were verified using ERRAT program. *On the error axis, two lines are drawn to indicate the confidence with which it is possible to reject regions that exceed that error value. **Expressed as the percentage of the protein for which the calculated error value falls below the 95% rejection limit. Good high resolution structures generally produce values around 95% or higher. For lower resolutions (2.5 to 3A) the average overall quality factor is around 91%.
