To appreciate the complexity of this task, one must first recognize that Cinnamycin is a 19 amino acid lantibiotic that presents unique challenges. Unlike standard chains, Cinnamycin is a tetracyclic antibacterial peptide produced by *Streptomyces cinnamoneus*. Its structure is defined by its post-translational modifications, specifically the presence of one lan by M Stawikowski · 2002 · Cited by 338 — This unit provides an overview of the field of synthetic peptides and proteins. It discusses selecting the solid support and common coupling reagents. thionine (Lan) and two methyllanthionine (MeLan) rings, alongside an unusual lysinoalanine (Lal) bridge.
When discussing how these peptides are constructed, it is clear that the primary hurdle is not just the linear sequence, but the precise formation of these macrocyclic bridges. My experience with laboratory-grade reagents suggests that the success of such an endeavor relies heavily on the strategy employed during the assembly phase.
