  • Ammonia-specific 5?-XMP aminase mutant
    Patent number: 8669078
    Abstract: Disclosed herein are ammonia-specific 5?-XMP aminase mutants and a method for preparing the same. A mutation is introduced into the active site of glutamine-dependent catalysis in 5?-XMP aminase. The resulting 5?-XMP aminase mutant is devoid of the glutamine-dependent activity and specifically reacts with external ammonia in converting 5?-XMP into 5?-GMP. Thus, the ammonia-specific 5?-XMP aminase mutant is stabler within cells compared to the wild type, and can be useful in the industrial conversion of 5?-XMP into 5?-GMP.
