PURPOSE:To prepare the titled substance in high yield, by transducing a gene of prephenate dehydrogenase obtained from DNA donor bacterium belonging to a bacterium capable of producing coryneform glutamic acid into a DNA receptor bacterium, cultivating the bacterium. CONSTITUTION:A gene of prephenate dehydrogenase connected to a vector plasmid capable of carrying out automatic replication in a mold of a bacterium capable of producing coryneform glutamic acid is obtained from a DNA donor bacterium belonging to a bacterium capable of producing coryneform glutamic acid. The gene is connected to the vector plasmid capable of carrying out automatic replication in a mold of a bacterium capable of producing coryneform glutamic acid, transduced into a DNA receptor bacterium belonging to a bacterium capable of producing coryneform glutamic acid, the prepared bacterium capable of producing L-phenylalanine is cultivated, and the desired substance is collected from the culture solution. |
