: Hydrostatic pressures (50 to 300 MPa) were applied at 0 °C for 50 min to determine the aggregation and viscoelastic properties of tilapia (Orechromis niloticus) myosin fragments: subfragment-1 (S-1) and rod. With pressure lower than 150-MPa treatment, S-1 underwent intermolecular interaction to increase its elastic properties. After a 200-MPa treatment, S-1 unfolded, aggregated, and decreased its solubility. A turbid solution was obtained after pressurization over 200 MPa. Further, S-1 transformed to a more elastic gel with pressure increasing. At 200 MPa, S-1 denatured entirely with no change of enthalpy detected by differential scanning calorimetry (DSC). However, all properties of rod did not change during pressurization. This study reveals that S-1 contributes the initiation of gel formation in myosin, and the role of rod is not clear. Keywords: hydrostatic pressure, S-1, rod, denaturation
