Electron-density maps near the M20 loop, NADP+ and FOL of the M20-closed crystal at (a) 0.1, (b) 400, (c) 650 and (d) 800 MPa. Electron density for the M20 loop and FOL are evident up to 400 MPa but become obviously weaker at 650 MPa. The electron-density map that covers key structures is shown at 1.0σ. |
