ABSTRACT:
A polypeptide comprising an amino acid sequence in which one or more amino acids are deleted, substituted or added in the amino acid sequence of a glutamine synthetase 2 derived from a microorganism belonging to a coryneform bacterium, wherein the coryneform bacterium producing the polypeptide has L-glutamine productivity, a DNA encoding the polypeptide, a recombinant DNA comprising the DNA, a microorganism comprising the DNA or the recombinant DNA, and a process for producing L-glutamine using the microorganism are provided.
