WebFeb 9, 2006 · All MHC proteins share approximately 100% conservation in the phosphate-binding loop, several helices forming the nucleotide-binding pocket, residues involved in actin binding, residues involved in the stereospecific hydrophobic rigor state interaction of actin with myosin, a cleft that divides the ATP- and actin-binding sites, and a converter ... 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).
