The delta-14 Mutation of Human Cardiac Troponin T Enhances ATPase Activity and Alters the Cooperative Binding of S1-ADP to Regulated Actin
(East Carolina University, 2004-12-07)
The complex of tropomyosin and troponin binds to actin and inhibits activation of myosin ATPase activity and force production of striated muscles at low free Ca2+ concentrations. Ca2+ stimulates ATP activity, and at ...
Equilibration and Exchange of Fluorescently Labeled Molecules in Skeletal Muscle Fibers Studied Using Confocal Microscopy
(East Carolina University, 1995-04)
Diffusion of molecules into skinned muscle fibers is often necessary when studying muscle contraction and its regulation. Usually, it is assumed that diffusion of molecules is fast also in the structured system of a muscle ...
