  • Title: Norleucine accumulation by a norleucine-resistant mutant of Serratia marcescens.
    Author: Kisumi M, Sugiura M, Chibata I.
    Journal: Appl Environ Microbiol; 1977 Aug; 34(2):135-8. PubMed ID: 334070.
    Abstract:
    A norleucine-resistant mutant was derived from an isoleucine-valine auxotroph of a leucine accumulator of Serratia marcescens. The norleucine-resistant mutant could accumulate norleucine from norvaline in the medium without the addition of methionine, which antagonized norleucine. This mutant constitutively formed homoserine-O-transsuccinylase.
