title: [Several peculiarities of the interaction of troponin T and troponin C of skeletal and cardiac muscle].
abstract: Using several independent methods, the interaction between troponin T and troponin C from skeletal and cardiac muscles was studied. It was found that troponin T and troponin C from skeletal muscles form a complex whose stability depends on Ca2+ concentration. Study of interactions between these troponin components demonstrated that both electrostatic and hydrophobic forces are involved in the complex formation. Cardiac troponin T and troponin C weakly interact with each other irrespective of experimental conditions. It was assumed that the weakening of interactions between the components of cardiac troponin is due to structural peculiarities of cardiac troponin T.
