by WA van der Donk · 2014 · Cited by 98 — Lantibiotics are a class of peptide-derived antimicrobial compounds that often disrupt the integrity of Gram-positive bacterial cell walls. TheUnderstanding the Structural Complexity
At the core of their function, these molecules are ribosomally synthesized and post-translationally modified antimicrobial peptides. The defining characteristic of these compounds is the presence of thioether amino acids, specifically lanthionine or methyllanthionine, which form polycyclic peptide antibiotics.
When discussing these compounds, it is essential to note that lanthipeptides possess antimicrobia Lantibiotics are a class of polycyclic peptide antibiotics that contain the characteristic thioether amino acids lanthionine or methyllanthionine, l activity, and in such cases, they are specifically referred to as lantibiotics. This classification is vital because Lantibiotics are a class of peptide-derived antimicrobial compounds that often function through specific mechanisms, such as binding to lipid II, a conserved precursor in bacterial cell walls.
Key Insights into Mechanisms
My experience in analyzing these peptides confirms that lanthipeptides are known antimicrobial agents with diverse applications.
