WebApr 7, 2024 · An additional smaller movement of phosphate-binding loop 1 (green, residues 14–16) can be noticed. (D) Tilted top view showing the movement of the two phosphate-binding loops. The switch loop known to be of importance for phosphate release follows the inward movement and is furthermore in direct contact with phalloidin (yellow). Walker A motif, also known as the Walker loop, or P-loop, or phosphate-binding loop, is a motif in proteins that is associated with phosphate binding. The motif has the pattern G-x(4)-GK-[TS], where G, K, T and S denote glycine, lysine, threonine and serine residues respectively, and x denotes any amino acid. It is present in many ATP or GTP utilizing proteins; it is the β phosphate of the nucleot…
