additional information the enzyme deaminates 5'-hydroxyl terminal adenosine residues in dinucleotides and trinucleotides, but not the 3'-hydroxyl terminal one in dinucleotides. The 5'-hydroxyl group of the ribose moiety is necessary for the substrate binding and catalytic activity of the squid enzyme Todarodes pacificus ?
