Genetic analysis of phenylalanine-responding mutants of Pseudomonas aeruginosa

A transduction analysis of phenylalanine-responding mutants of Pseudomonas aeruginosa revealed the existence of six unlinked genes. Enzyme assays showed that one gene was involved in the terminal production of phenylalanine (chorismate mutase), and the remaining five genes were involved in the common pathway of aromatic amino acid biosynthesis.
