Abstrakt: Develops a procedure for enzymatic synthesis of 2-deoxyguanosine, consisting of the transglycosylation from thymidine to 6-substituted purine (2-amino-6-chloropurine) instead of natural guanine and the conversion of 2-amino-6-chloropurine-2-deoxyriboside to dGuo with bacterial adenosine deaminase. Reaction efficiencies of NdRT-II; Types of NPases needed in the transglycosylation reaction of DAPdR or ACPdR production from dThd by a nucleotide phosphorylase.
