Abstract The effect of NaCl (0.1 − 3.0 M) on self-assembly of silver carp myosin at 4 °C was investigated in terms of microstructure, conformation, intermolecular interactions, and particle size distribution. During setting at 4 °C, the self-assembly of myosin showed an obvious concentration dependence. At low concentrations ( 2+ -ATPase activity reached a maximum at 0.6 M NaCl. When the concentrations increased to >1.0 M, myosin further assembled into filaments dominated by hydrophobic interactions. Both rod-rod and head-head interactions contributed to the myosin filaments at high concentrations (1.0 − 3.0 M). The solubility and uniformity of the myosin assemblies decreased as the NaCl concentration increased from 1.0 to 3.0 M.
