The PDB accession codes correspond to the following HPt structures: 1oxk, Saccharomyces cerevisiae; 1yvi, Oryza sativa; 1wn0, Zea mays
Q-score represents the quality function of Cα alignment. It reduces the effect of RMSD - Nalgn (number of aligned residues) balance on the estimation of alignments (Nres1 and Nres2 stand for the number of residues in the aligned proteins, and the empirical parameter R0 is set to 3 Å): Q = (Nalgn·Nalgn)/[(1+(RMSD/R0)2)·Nres1·Nres2]
