EPPIC (Evolutionary Protein-Protein Interface Classifier) provides value-added information about biological assemblies in the PDB. This web server classifies interfaces present in protein crystals to distinguish biological interfaces from crystal contacts. The latest version of EPPIC (v3) now enumerates all possible symmetric assemblies with a prediction of the most likely assembly based on probabilistic scores from pairwise evolutionary scoring. EPPIC is now fully hosted and supported at RCSB PDB.
A detailed description was recently published:
EPPIC was also highlighted in the PLOS BIOLOGUE.
The EPPIC project was initiated by Guido Capitani at the Paul Scherrer Institut. Guido sadly passed away in 2017. He was a good friend and colleague and will be missed.
