Abstract

The invention provides a method for producing a cytosine nucleoside compound from pentose-1-phosphate and cytosine or a derivative thereof using a nucleoside phosphorylase reactive to cytosine or a bacterium having the enzyme activity. The invention also provides a method for specifically reducing an activity to degrade the substrates or the product, resulting in efficient production of the cytosine nucleoside compound. According to the invention, little by-product is produced in producing cytonucleocide compounds.
