Fig. 2

Communication Blocks of MeV PMD, NiV PMD and RhcC identified by COMMA2. \(CBs^{path}\) and \(CBs^{clique}\) identified by COMMA2 are mapped on the structure of a–c MeV PMD (PDB code: 3ZDO), d–f NiV PMD (PDB code: 4N5B) and g–i RhcC (PDB code: 1YBK). Left a, d, g Distinct \(CBs^{path}\) of at least 4 residues are colored in shades of red. Middle b, e, h long-range \(CBs^{path}\) are depicted in shades of purple, containing at least 7 residues (for NiV PMD) or 8 residues (for MeV PMD and RhcC). Right c, f, i distinct \(CBs^{clique}\) are colored in blue tones. Residues known to be ambiguous in MeV PMD are shown by sticks
