The effect of pressure treatment (1 atm ∼ 5000 atm) on flying fish and sardine actomyosin ATPases was studied from the standpoint of interaction between myosin and actin. The activities of actomyosin Mg-ATPases markedly decreased and those of the EDTA-ATPases rapidly increased with prolonged pressure treatment at 3000 atm and 5000 atm. Changes in activities of F-actin plus pressure-treated myosin Ca-ATPases showed results similar to those of pressure-treated actomyosin Ca-ATPases, while myosin plus pressure-treated F-actin resulted in decreased Mg-ATPase activity and increased EDTA-ATPase activity.
