Ca2+ and Ionic Strength Dependencies of S1-ADP Binding to Actin-Tropomyosin-Troponin: Regulatory Implications
Gafurov, Boris; Chen, Yi-Der; Chalovich, Joseph (East Carolina University, 2004-09)Skeletal and cardiac muscle contraction are inhibited by the actin-associated complex of tropomyosin-troponin. Binding of Ca21 to troponin or binding of ATP-free myosin to actin reverses this inhibition. Ca21 and ATP-free ... -
Characterization of a caldesmon fragment that competes with myosin-ATP binding to actin.
Velaz, Laly; Chen, Yi-Der; Chalovich, Joseph (East Carolina University, 1993-08)The protein caldesmon inhibits actin-activated ATP hydrolysis of myosin and inhibits the binding of myosin*ATP to actin. Afragment isolated from a chymotryptic digest of caldesmon contains features of the intact molecule ... -
Kinetics of Binding of Caldesmon to Actin
Chalovich, Joseph; Chen, Yi-Der; Dudek, Ronald W.; Hai, Luo (East Carolina University, 1995-04-28)The time course of interaction of caldesmon with actin may be monitored by fluorescence changes that occur upon the binding of 12-(N-methyl-N-(7-nitrobenz-2-oxa-l,3-diazol-4-yl))-labeled caldesmon to actin or to acrylodan ...
