Nisin, a peptide antibiotic: cloning and sequencing of the nisA gene and posttranslational processing of its peptide product

Open access

Abstract

Nisin produced by Streptococcus lactis is used as a food preservative and is the most important member of a group of antibiotics containing lanthionine bridges. To understand the genetic basis of these so-called lantibiotics (Schnell et al., Nature 333:276-278, 1988), we characterized the nisin structural gene, nisA, which is located on a plasmid and codes for a 57-amino-acid prepeptide. The prepeptide is processed posttranslationally to the pentacyclic antibiotic. Although nisin and the recently elucidated lantibiotic epidermin from Staphylococcus epidermidis are produced by different organisms, their gene organization is identical. As with epidermin, the nisin propeptide corresponds to the C-terminus of the prepeptide. The N-terminus of the prepeptide is cleaved at a characteristic splice site (Pro--2 Arg--1 Ile-+1). Remarkably, the N-terminus of prenisin shares 70% similarity with preepidermin, although the propeptide sequences are distinctly different. The structural similarities between these two lantibiotics are consistent with the fact that there is a common mechanism of biosynthesis of these lanthionine-containing antibiotics.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
