fragments of rabbit skeletal muscle ca2+-binding subunit of troponin ( tnc ) , obtained by cleavage with trypsin , thrombin , and cnbr , were tested for their ability to form binary and ternary complexes with atpase inhibitory subunit ( tni ) and tropomyosin-binding subunit ( tnt ) and their ability to replace tnc in reversing tni inhibition of actomyosin atpase activity .
