Using NMA and SAXS to derive the open model of BlaC. (A) The SREFLEX derived model and the crystal structure overlaid on each other. The loop showing the most prominent change is highlighted by a black arrow. (B and C) The fit between the theoretical SAXS profiles and distance distribution functions of closed form of BlaC, as seen in the crystal structures, and the open form derived by SREFLEX with the experimental data. (D) An overlay of the SAXS model of BlaC in Apo state with the crystal structure and SREFLEX derived model (Left), followed by two orthogonal views without the water molecules.
