Coot

Coot is a powerful macromolecular model-building tool for

analysing X-ray data and models (i.e. proteins, ligands, RNA and

DNA). There are many tools for model manipulation and building,

such as minimization, molecular superposition, fragment

rotation/translations, rotamer-fitting, de novo building and

refinement.

Coot is used by scientists using X-ray crystallography or cryo-EM for

analysis of proteins, electron density maps, protein interactions

and drug design.
