Abstract

The present disclosure relates to a modified polypeptide of glutamine synthetase having enhanced activity and a method of producing L-glutamine using the same. Since production of L-glutamine may be increased by using the novel modified polypeptide without a decrease in a growth rate compared to wild-type strains having glutamine synthetase activity, the modified polypeptide may be widely used for mass production of L-glutamine.
