More Information
Summary:Disclosed are: a polypeptide which is characterized in that the polypeptide comprises an amino acid sequence having the deletion, substitution or addition of at least one amino acid residue in the amino acid sequence for glutamine synthetase 2 derived from a microorganism belonging to the genus Corynebacterium, and that a Corynebacterium capable of producing the polypeptide can produce L-glutamine; DNA encoding the polypeptide; recombinant DNA carrying the DNA; a microorganism harboring the DNA or the recombinant DNA; and a method for production of L-glutamine using the microorganism. L'invention concerne un polypeptide caractérisé par le fait qu'il comprend une séquence d'acides aminés présentant une suppression, substitution ou addition d'au moins un résidu acide aminé dans la séquence d'acides aminés de la glutamine synthétase 2 dérivée d'un micro-organisme appartenant au genre Corynebacterium et par le fait qu'une corynébactérie capable de produire le polypeptide peut produire de la L-glutamine ; un ADN codant pour le polypeptide ; un ADN recombinant portant l'ADN ; un micro-organisme contenant cet ADN ou ADN recombinant ; et un procédé de production de L-glutamine en utilisant le micro-organisme.
