Hierarchical cluster analysis of different types of A_−1A and A_−1B demonstrating the capacity of the TSR algorithm, which can distinguish their 3D structural differences. Panel a, the hierarchical cluster analysis of 3D structural relationships of A_−1A and A_−1B. The numbers of A_−1A and A_−1B are labeled; panel b, the structural similarity between A_−1A—A_−1A pairs, A_−1B—A_−1B pairs and A_−1A—A_−1B pairs. The average similarity values, SDs, and 25/75 percentiles are indicated; panel c, the Venn diagram showing the numbers of TSR keys exclusively belonging to the A_−1A group, the A_−1B group and the intersection between the A_−1A group and the A_−1B group; panel d, the distinct, total, distinct common (C_Distinct), total common (C_Total), distinct specific (S_Distinct) and total specific (S_Total) TSR keys for A_−1A and A_−1B. The average values and SDs are indicated; panel e, the ten A_−1A specific TSR keys. The amino acids associated with these ten keys are PsaA-L673, PsaA-H676, PsaA-F677, PsaB-F578, PsaB-W579, PsaB-N582 and PsaB-W586. The PDB is 5OY0
