Abstract
There is provided a method for producing L-leucine using bacterium belonging to the genus, which produces L-valine, L-isoleucine and L-homoleucine in an amount of less than 1% of that of L-leucine produced due to inactivation of ilvE gene coding for branched chain amino acid transaminase and produces increased amount of L-leucine due to increasing the activity of the aromatic amino acid transaminase encoded by tyrB gene.
