Abstract
Abstract The present invention relates to a process for producing an aromatic amino acid which comprises culturing a Coryneform bacterium carrying a recombinant DNA constructed by connecting (1) a gene capable of being expressed in a Coryneform bacterial cell and coding for 3-deoxy-D-arabino-heptulonic acid-7-phosphate synthetase with (2) a plasmid vector capable of propagating in a Coryneform bacterial cell.
