MetalS3 is a tool to search the MetalPDB database for metal sites having a 3D structure similar to that of the input. It outputs a list of candidate sites with a similarity score better than an arbitrary threshold, adjustable also after the end of the calculation as a list filter.

MetalS3 is based on the algorithm of MetalS2, a tool designed to optimally superimpose two input metal sites.

MetalPDB collects and allows easy access to the knowledge on metal sites in biological macromolecules, starting from the structural information contained in the Protein Data Bank (PDB)
