The purine analog, 2-chloro-2'-deoxyadenosine triphosphate (CldATP), was incorporated enzymatically in place of dATP into the minus strand of M13mp18 duplex DNA. Its effect on protein-DNA interactions was assessed by determining the amount of DNA cleavage by type II restriction endonucleases.

Cladribine (2-chloro-2'-deoxyadenosine) was synthesized using intact cells of the recombinant Escherichia coli strain producing Geobacillus stearothermophilus B-2194 thermostable purine-nucleoside phosphorylase II (EC 2.4.2.1). Use of the cells containing this thermostable enzyme allowed the process to be conducted at a temperature
