DALI output describes the following :

Z score , the statistical significance of the similarity between protein-of-interest and other neighbourhood protines. The program optimises 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. As in indicated in DALI, rmsd is not optimised 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.

The P-loop connecting b1 and a1, has well conserved sequences, and its amino acid side chains exhibit the same conformations among all other proteins with the GXXXXGKT motif.Other conserved motifs are also observed in MinD. The Walker B motif (residues 118±121) is located near the terminus of b5, and has the modi®ed sequence, Asp-XPro- Ala.Image constructed from PyMOL
