Abstract
A partition equilibrium study has shown calcium ion to be a noncompetitive inhibitor of aldolase adsorption by rabbit muscle myofibrils. This inhibition is interpreted quantitatively in terms of a 10-fold decrease in the intrinsic association constant for the aldolase-myofibril interaction upon Ca2+ binding to either or both of the low-affinity troponin sites associated with regulation of muscle contraction.Entities:
