FACE2FACE is a web-based service to analyse interfaces between biological macromolecules.
- The input file must contain atomic coordinates in PDB format.
- At least two macromolecule chains must be present.
- Each chain may belong to either a protein or a nucleic acid.
- Both standard (e.g., solvent accessibility, secondary structures and hydrogen bonds) and non standard (e.g., non polar contacts, atoms involved in the interactions) structural information are calculated.
