Structure Similarities

Z score , the statistical significance of the similarity between protein-of-interest and other neighbourhood proteins. The program optimizes a weighted sum of similarities of intramolecular distances.

Root Mean Square Distance (RMSD), root-mean-square deviation of C-alpha atoms in the least-squares superimposition of the structurally equivalent C-alpha atoms. RMSD is not optimized and is only reported for information.

lali, the number of structurally equivalent residues.

nres, or the total number of amino acids in the hit protein.

%id, percentage of identical amino acids over structurally equivalent residues.
