Amino Acid-β-Naphthylamide Uptake by Pseudomonas aeruginosa

Abstract

Studies on the arylamidase of Pseudomonas aeruginosa indicate that the enzyme is intracellular and constitutive. However, in cells grown in a basal salts medium, the uptake of amino acid-β-naphthylamide is induced by certain amino acids. The synthesis of protein(s) related to transport in response to exposure to amino acids is postulated since chloramphenicol completely inhibits the inducing effect of amino acids. The uptake of amino acid-β-naphthylamide is energy dependent, and the amino acid residue is incorporated into bacterial protein.
