1 By introducing point mutations into a subdomain interface at the base of the myosin lever arm at positions Lys(84) and Arg(704), we caused modulatory changes in the equilibrium constant of the recovery stroke, which we could accurately resolve using the fluorescence signal of single tryptophan Dictyostelium myosin II constructs.
