Biosynthesis, Molecular Regulation, and Application of Bacilysin Produced by Species.

Microbes produce a diverse range of secondary metabolites in response to various environmental factors and interspecies competition. This enables them to become superior in a particular environment. Bacilysin, a dipeptide antibiotic produced by species, is active against a broad range of microorganisms. Because of its simple structure and excellent mode of action, i.e., through the inhibition of glucosamine 6-phosphate synthase, it has drawn the attention of researchers. In addition, it acts as a pleiotropic signaling molecule that affects different cellular activities. However, all species are not capable of producing bacilysin. The biosynthesis of bacilysin by species is not uniform throughout the population; specificity and heterogeneity at both the strain and species levels has been observed. This review discusses how bacilysin is biosynthesized by species, the regulators of its biosynthesis, its importance in the host, and the abiotic factors affecting bacilysin production.
