Abstract: A process for the microbial production of aromatic amino acids and other metabolites of the aromatic amino acid biosynthetic pathway The invention relates to a process for the microbial production of aromatic amino acids and other metabolites of the aromatic amino acid biosynthetic pathway. Microbially produced substances such as fine chemicals, in particular aromatic amino acids or metabolites of the aromatics biosynthetic pathway, are of great economic interest, and the need for amino acids, for example, continues to increase. The inventors found that, after introducing a pyc gene sequence into microorganisms, it was possible to produce aromatic amino acids and also metabolites of the aromatic biosynthetic pathway in an improved manner. The process of the invention is particularly suitable for producing L-phenylalanine.
