Rapid Reversal of Ethionine Inhibition of Enzyme Induction in Pseudomonas aeruginosa by L- and D-methionine

Summary

1) Ethionine inhibition of induction of enzymes involved in benzoate oxidation by washed cell suspensions of Pseudomonas aeruginosa is rapidly reversed by L-methionine and almost as rapidly by D-methionine. Neither amino acids nor ethionine have any effect once the enzymes have been induced. Similar results were obtained with p-fluorophenylalanine.
