Complementarity plot

A pictorial description of the Complementarity Plot with its different regions
Distribution of points in the Complementarity Plot corresponding to buried amino acid side-chains from a high resolution protein crystal structure

The complementarity plot (CP) is a graphical tool for structural validation of atomic models for both folded globular proteins and protein-protein interfaces.[1][2][3] It is based on a probabilistic representation of preferred amino acid side-chain orientation, analogous to the preferred backbone orientation of Ramachandran plots). It can potentially serve to elucidate protein folding as well as binding. The upgraded versions of the software suite is available and maintained in github for both folded globular proteins[4] as well as inter-protein complexes.[5] The software is included in the bioinformatic tool suites OmicTools[6] and Delphi tools.[7]
