BriX applications: ‘covering’ and ‘bridging’. (A) Covering: an input PDZ structure (PDB: 2WL7) is shown for which the algorithm finds matching structural fragments for the β-strand starting at residue 112 in chain A (red). The algorithm returns a set of protein fragment structures (green) superposed on the β-strand, together with structure and sequence logos. (B) Bridging: the same PDB structure (PDB: 2WL7), now with a missing loop. The algorithm finds loop fragments that match the regular anchor residues 104 and 112 spanning the loop with the same end-to-end distance (green).
