Mutant strain of E. coli having resistance to decoyinine

摘要

The present invention is a 5'-5'xanthan tilsan derived from E. coli necessary for the reaction for conversion into GMP in (XMP) 5'xanthan tilsan transaminase (XMP aminase) in the manufacture of a guanylate (GMP) from the inhibition by high concentrations GMP disabling the invention relates to its non-mutant E. coli enzyme activity the method of GMP using KD113, and this has a decor coix seed resistance obtained by processing a mutagen for the purpose of increasing the character (specific activity) and.
