PubMed Abstract: Nucleoside 2-deoxyribosyltransferase plays an important role in the salvage pathway of nucleotide metabolism in certain organisms, catalyzing the cleavage of beta-2'-deoxyribonucleosides and the subsequent transfer of the deoxyribosyl moiety to an acceptor purine or pyrimidine base. The kinetics describe a ping-pong-bi-bi pathway involving the formation of a covalent enzyme-deoxyribose intermediate. The enzyme is produced by a limited number of microorganisms and its functions have been exploited in its use as a biocatalyst to synthesize nucleoside analogs of therapeutic interest.
