MotiveValidator
MotiveValidator is a platform for a set of applications designed to help you determine whether a residue or a ligand in a biomolecule or biomolecular complex is structurally complete and correctly annotated according to reference structural models stored in the wwPDB Chemical Component Dictionary.
The applications provided within the MotiveValidator platform cover all standard and nonstandard residues defined in the wwPDB Chemical Component Dictionary database. In addition, you may specify your own reference template of a residue (i.e., model) if it is not available in wwPDB Chemical Component Dictionary.
