Lantibiotic nisin-Z

Gene

nisZ

Organism
Lactococcus lactis subsp. lactis (Streptococcus lactis)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Lanthionine-containing peptide antibiotic (lantibiotic) active on Gram-positive bacteria. The bactericidal activity of lantibiotics is based on depolarization of energized bacterial cytoplasmic membranes, initiated by the formation of aqueous transmembrane pores.

Post-translational modificationi

Maturation of lantibiotics involves the enzymic conversion of Thr, and Ser into dehydrated AA and the formation of thioether bonds with cysteine. This is followed by membrane translocation and cleavage of the modified precursor.
The structure of the 2,3-didehydrobutyrine is not discussed in PubMed:15361862. It is probably the Z-isomer by similarity.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
