PRODUCTION OF NUCLEOSIDE. |
摘要 |
This invention relates to a method of producing a nucleoside by reacting a base donor, a sugar residue donor, and a phosphate donor with one another in the presence of an enzymatic preparation containing a nucleoside phosphorylase to thereby form an N-glycoside linkage between a base portion of the base donor and a sugar residue portion of the sugar residue donor, characterized in that said enzymatic preparation containing a nucleoside phosphorylase is one based on the cells of at least one microorganism selected from among those belonging to thermophilic bacteria of the genus Bacillus and having a high nucleoside phosphorylase activity per unit weight of the cell. |
