Solid-phase peptide synthesis (SPPS) is a crucial technique for the laboratory production of peptides, including complex molecules like lichenicidin, a potent lantibiotic. Lichenicidin, produced by *Bacillus licheniformis*, is a two-peptide antimicrobial substance that exhibits activity against a broad spectrum of bacteria.作者：IS Panina·2023·被引用次数：19—Specific Binding of the α-Component of the LantibioticLichenicidinto the Peptidoglycan Precursor Lipid II Predetermines Its Antimicrobial Activity. by. Irina ... While its natural biosynthesis involves intricate post-translational modifications, SPPS offers a controlled and versatile method for its chemical synthesis, enabling detailed study of its structure, function, and potential therapeutic applications.
Lichenicidin is a lantibiotic, a class of ribosomally synthesized and post-translationally modified peptides characterized by the presence of lanthionine and methyllanthionine cross-links. It comprises two distinct peptide components, often referred to as the α-component and the β-component, which work synergistically to exert antimicrobial activity. The α-component of lichenicidin has been shown to bind specifically to lipid II, a precursor molecule in peptidoglycan biosynthesis, thereby disrupting bacterial cell wall formation.Biotechnological Production of the Recombinant Two ... Understanding these components is vital for both their production and for elucidating their mechanism of action.
Solid-phase peptide synthesis is a method where amino acids are sequentially added to a growing peptide chain anchored to an insoluble solid support, typically a resin. This approach offers significant advantages over traditional solution-phase synthesis, including simplified purification steps, as excess reagents and byproducts can be easily washed away from the solid support.Lanthipeptides: chemical synthesis versus in vivo biosynthesis ...

Subsequent amino acids, protected at their N-termini and activated at their carboxyl termini, are then coupled to the free N-terminus of the growing peptide chain. This cycle of deprotection and coupling is repeated until the desired peptide sequence is assembled.
