Lectoine
Lectoine are a class of small, cyclic peptides produced by certain extremophilic bacteria, most notably from the genus *Streptomyces*. These peptides are characterized by their unique structure, which often includes unusual amino acids and a ring-like conformation. Lectoine are primarily known for their ability to protect cells from various environmental stresses.
The primary function attributed to lectoines is osmoprotection. This means they help cells maintain their internal
The biosynthesis of lectoines involves non-ribosomal peptide synthetases (NRPS), complex enzyme machinery that assembles the peptide
