Abstract

The use of bacterial trans-N-deoxyribosylase was evaluated as an alternative method for deoxyribosylation in the synthesis of deoxyribonucleosides containing potentially mutagenic adducts. A crude enzyme preparation was isolated from Lactobacillus helveticus and compared to Escherichia coli purine nucleoside phosphorylase. trans-N-deoxyribosylase was more regioselective than purine nucleoside phosphorylase in the deoxyribosylation ...
