  • Title: Isoleucine accumulation by regulatory mutants of Serratia marcescens: lack of both feedback inhibition and repression.
    Author: Kisumi M, Komatsubara S, Sugiura M, Chibata I.
    Journal: J Bacteriol; 1972 May; 110(2):761-3. PubMed ID: 4553844.
    Abstract:
    Double mutants of Serratia marcescens resistant to isoleucine hydroxamate and alpha-aminobutyric acid accumulated large amounts of isoleucine in a salts-sugar medium and lacked both feedback inhibition and repression of the isoleucine biosynthesis.
