METHODS FOR PREPARING 3'-AMINO-2',3'-DIDEOXYGUANOSINE BY USING NUCLEOSIDE PHOSPHORYLASES DERIVED FROM BACILLUS AND ADENOSINE DEAMINASE DERIVED FROM LACTOCOCCUS

摘要

The present invention relates to a method for preparing 3'-amino-2',3'-dideoxyguanosine using Bacillus stearothermophilus-derived nucleoside phosphorylases and Lactococcus lactis-derived adenosine deaminase. According to the method for preparing 3'-amino-2',3'-dideoxyguanosine of the present invention, 3'-amino-2,3'-dideoxyguanosine can be mass-produced efficiently and economically through high rate of enzymatic conversion and high purity of purifications.
