ABSTRACT:
The present invention provides a microorganism for producing a 2′-deoxyribonucleoside. In particular, the microorganism of the present invention is transformed with a gene encoding a ribonucleotide reductase and in which 2′-deoxyribonucleoside degradation activity is decreased or eliminated by disrupting a gene encoding a purine nucleoside phosphorylase on chromosomal DNA.
