Tropomyosin Period 3 Is Essential for Enhancement of Isometric Tension in Thin Filament-Reconstituted Bovine Myocardium

Figure 9

Summary of the temperature effect on isometric tension (a) and stiffness (b). The mean and SEM are shown. The number of experiments is nfTm ( ), ( ), ( ). Under the experimental conditions used here (standard activation solution and the constant sarcomere length), the larger temperature sensitivity corresponds to an increased hydrophobic interaction between actin and myosin molecules [24].
