Characterization of a caldesmon fragment that competes with myosin-ATP binding to actin.
(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 ...
Localization and Characterization of a 7.3-kDa Region of Caldesmon Which Reversibly Inhibits Actomyosin ATPase Activity
(East Carolina University, 1992-08-15)
Cleavage of caldesmon with chymotrypsin yields a series of fragments which bind both calmodulin and actin and inhibit the binding of myosin subfragments to actin and the subsequent stimulation of ATPase activity. Several ...
