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.
