Nucleoside-5'-phosphate ester is producedninexpensively and efficiently by allowing an acidnphosphatase, especially an acid phosphatase having anlowered phosphomonoesterase activity to act under ancondition of pH 3.0 to 5.5 on a nucleoside and anphosphate group donor selected from the group consistingnof polyphosphoric acid or a salt thereof,nphenylphosphoric acid or a salt thereof, and carbamylnphosphate or a salt thereof to produce nucleoside-5'-phosphatenester, and collecting it. |
