The enzymes adenosine deaminase (ADA) and adenylate deaminase (AMPDA) are able to catalyze the hydrolytic dechlorination of 6-chloropurine riboside and the corresponding 2′,3′-O-isopropylidene derivative, but show no activity towards the 3,4-O-isopropylidene-1-methylriboside of 6-chloropurine and adenine.
