  • Title: Effect of calcium ion on the interaction of aldolase with rabbit muscle myofibrils.
    Author: Harris SJ, Winzor DJ.
    Journal: Biochim Biophys Acta; 1989 Nov 09; 999(1):95-9. PubMed ID: 2804142.
    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.
