The Architecture of LAPs
At their core, linear azol(in)e-containing peptides are defined by their non-macrocyclic nature and the presence of specific heterocycles. When I examine the literature, it becomes clear that these compounds are multi-source—originating from diverse organisms ranging from bacteria to complex eukaryotes. The primary structural markers that distinguish them are the thiazole and (methyl)oxazole rings. These are formed through a sophisticated process of cyclodehydration of serine, threonine, or cysteine residues, followed by oxidation—a hallmark of the linear azol(in)e signature.
Defining Characteristics
* Terminology: You will often see them referred to as linear azole-containing peptides or the broader linear azo(lin)e peptide (LAP) family member category.
* Biosynthesis: Unlike standard polypeptides, these undergo rigorous post-translational modifications (PTMs). Enzymes like MprC facilitate the initial cyclodehydration, while MprD manages the oxidation steps to stabilize the azol(in)e rings.
* Structural Diversity: Their linear architecture allows for distinct interaction profiles compared to cyclic counterparts like thiopeptides.
