Aurintricarboxylic acid (ATA) has been previously categorized as a drug which inhibits enzymes of polynucleotide metabolism. In this paper we present evidence that ATA does not show specificity toward this class of enzymes only. Rather, the drug will bind to and inhibit most enzymes regardless of their specific catalytic function.
