(a) Temperature dependence of 2${\text{A}}_{\text{zz}}^{\prime }$ of MSL–formin as a function of temperature. At approximately 41 °C a breakpoint is apparent. (b) Temperature dependence of the hyperfine splitting constants of: MSL–formin complex with F-actin (1:5 mol/mol) (filled squares), MSL–F-actin complex with formin (5:1 mol/mol) (asterisks), and MSL–F-actin without formin (filled triangles)
