Nisin biosynthesis
WebbAdditionally nisin can auto-regulate its own biosynthesis via the two component system encoded on the genes nisK and nisR. Nisin Biosynthesis . Nisin is ribosomally synthesized as a 57 amino acids long prepeptide. The prepeptide is subdivided in a N-terminal leader peptide comprising 23 amino acids and a 34 amino acid long propeptide. WebbNisin was produced only when the leader consisted mainly of the nisin part. This indicates that nisin and its leader sequence might work as a couple that makes a recognizable …
