Calponin, an actin-binding protein, inhibited the acto-heavy meromyosin (HMM) MgATPase and lowered the binding of HMM to actin. The amount of calponin bound to actin or tropomyosin-actin was the same when the ATPase was inhibited 80–90%. While the KATPasewas diminished only less than 2-fold in the presence of calponin, the Vmaxwas decreased 6-fold and 2-fold with actin and tropomyosin-actin, respectively. A comparison of the kinetic constants for the ATP hydrolysis obtained in the presence of actin-calponin and tropomyosin-actin-calponin revealed that the tropomyosin augmented the Vmax5-fold from the inhibited level, but there was no effect on the KATPase.
