Single mutation protein structure pairs extracted from the PDB with MicroMiner

This page provides the single mutation data extracted with MicroMiner from the PDB. The data contains amino acid pairs in protein structures from the PDB, exemplifying single mutations’ local structural changes for single chains and pairs for protein–protein interfaces. Mutations to non-standard residues are also provided.<br> See the MicroMiner publication for details: <em>Sieg, J.; Rarey, M.

Multiple local structural and sequential similarity measures are provided, computed from the residue 3D micro-environments. The column fullSeqId contains the global sequence similarity.
