title: The ability of salts to inhibit the reaction between periodate anions and ovotransferrin.
abstract: The reaction between periodate anions and apo-ovotransferrin results in the rapid abolition of the iron-binding ability of the protein and the loss of approximately 4 mol of tyrosine/mol of protein. The degree of inhibition exerted by a variety of salts on the rate of this reaction is found to be inconsistent with the lyotropic series and suggests the existence of a complex anion-binding site in the apoprotein. The existence of this site may explain the action of periodate anions on ovotransferrin.
