Click at two points in the protein for the refinement. Optimizes the stereochemistry of a region (bond length/angles). B efore accepting the new position you can manually pull the chain to change it’s way. Refines region based on the electron density map: Click at two points in the protein or click one residue and press “A” for a residue restricted Refinement. I will orientate my explanation on that image: Real Space Refine Zone* Overwrite protection: Ask before overwriting fileģ.) Understanding the basic refinement tools.Always sort by date (currently only for selector)? Yes.File Selector/Chooser? Classic File Selector.loading in the phase information (.mtz.): File –> Auto Open MTZ... OR Open MTZ, mmCIF, fcf or phs….loading in the structure model (.pdb): File –> Open Coordinates….mtz file using: coot -pdb refine.pdb -auto refine.mtz

mtz file that can be retrieved from the PDB database as well.

This data is not stored in your typical PDB file, but in a seperate. The adjustment of the structure in Coot is done on the basis of the electron density can was calculated during the X-ray diffraction experiment. mtz file, we can place a model inside this coarse grid and refine the model further using other program, such as PHENIX, REFMAC or buster/TNT. From the determined phases and the initial. The refinement itself is an iterative process. It can be used to validate and refine crystal structures of proteins. Coot is the main tool used in the field of crystallography for macromolecular model building especially using X-ray data.
