Application


  • Synthesis of the lantibiotic lactocin S using peptide cyclizations on solid phase.: This research highlights innovative methods for synthesizing peptide-based antibiotics like lactocin S, utilizing dl-lanthionine to form crucial thioether crosslinks that enhance the activity and stability of these peptides (Ross et al., 2010).

  • Cystathionine gamma-lyase of Streptomyces phaeochromogenes.: This research documents the isolation and characterization of an enzyme that processes cystathionine, which involves dl-lanthionine as a structural analog, revealing its role in bacterial physiology and potential applications in biotechnology (Nagasawa et al., 1984).

  • The availability of dl-lanthionine for the promotion of growth in young rats when added to a cystine- and methionine-deficient diet.: This historical study explores the nutritional value of dl-lanthionine, investigating its ability to substitute for essential amino acids in growth diets, which helps in understanding its potential use in nutritional supplements (Jones et al., 1948).

Biochem/physiol Actions

Lanthionine is a non-typical amino acid and a monosulfide analog of cystine. Lanthionines are constituents of a group of peptide antibiotics called lantiobiotics, which include nisin and subtilin.
