... His145Asn mutations on the affinity of metal binding to arginase II To further examine the effects of the His120fiAsn and His145fiAsn mutations on the interaction of the enzyme with manganese ions, ... addition to removal of the more weakly bound Mn 2+ , the lower affinity for that more tightly bound to the protein may explain the absence of Mn 2+ from the EDTA-tre...
