  • Title: Chemical modification of the actin binding site of rabbit muscle aldolase by diethylpyrocarbonate.
    Author: Don M, Masters C.
    Journal: Mol Cell Biochem; 1988 Jun; 81(2):145-53. PubMed ID: 3173350.
    Abstract:
    To extend the available information on the significance of the interactions between glycolytic enzymes and the actin component of the cellular ultrastructure, investigations into the compositional characteristics of the actin binding site on one of the major glycolytic enzymes, aldolase, have been undertaken. As the electrostatic nature of the association has been previously reported indicative of a cationic region on the enzyme involved in the binding, these studies have investigated the possibility of the involvement of histidine residues in this binding region. By the use of the histidine specific reagent, diethylpyrocarbonate, we have been able to establish a difference in nature of an actin binding domain and the active site domain which does contain an essential histidine. The results have been discussed in relation to the significance of this finding with respect to the binding of aldolase to subcellular structure.
