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.
