Web21. feb 2024 · Since the sequence of M13 ssDNA is different from one filament to another, a poly-dT (thymine) DNA molecule was built in these averaged densities. Finally, ATPγS molecules were built in the corresponding densities of the map. SpRecA model with ssDNA and ATPγS was refined against the cryoEM map using real-space refinement in Phenix . WebYou will see a list of molecule that include the text you typed as part of the molecule names. If you click on any of those buttons, Coot runs LIBCHECK and generates a molecule and puts it at the centre of the screen. You can do this for the 3 or 4 different molecules that you think this blob might be. The centre of the screen is a bit crowded now. http://www.uoxray.uoregon.edu/local/manuals/phenix-1.24.1b/phenix/structure_refinement.html showa 47 stiction
