More Information
Summary:The present invention relates to a method for producing L-amino acids, such as L-tryptophan, L-phenylalanine and L-tyrosine, using a bacterium belonging to the genus Escherichia, and wherein the L-amino acid productivity of said bacterium is enhanced by enhancing an activity of PEP carboxykinase, which is coded by the pckA gene. La présente invention concerne un procédé de production de L-acides aminés, tels que le L-tryptophan, la L-phénylalanine et la L-tyrosine, à partir d'une bactérie appartenant au genre Escherichia. Pour augmenter la production de L-acides aminés à partir de ladite bactérie, on améliore l'activité de la PEP carboxykinase, codée par le gène pckA.
