Identification and characterization of the lantibiotic nisin Z, a natural nisin variant

Identification and characterization of the lantibiotic nisin Z, a natural nisin variant Lactococcus lactis strain NIZO 22186 produces an extracellular, lanthinine‐containing 3.5‐kDa polypeptide with antimicrobial activity. Its retention time on reversed‐phase (RP) HPLC and its amino acid composition showed high similarities but no complete identity to nisin. The gene for this lantibiotic, designated nisZ, has been cloned and its nucleotide sequence was found to be identical to that of the precursor nisin gene apart from a single mutation resulting in the substitution His27Asn in the mature polypeptide. NMR studies of the natural nisin variant, which has been designated nisin Z, confirmed the His27Asn substitution and idicated that it has a similar structure to nisin. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png The Febs Journal Wiley

Abstract

Lactococcus lactis strain NIZO 22186 produces an extracellular, lanthinine‐containing 3.5‐kDa polypeptide with antimicrobial activity. Its retention time on reversed‐phase (RP) HPLC and its amino acid composition showed high similarities but no complete identity to nisin. The gene for this lantibiotic, designated nisZ, has been cloned and its nucleotide sequence was found to be identical to that of the precursor nisin gene apart from a single mutation resulting in the substitution His27Asn in the mature polypeptide. NMR studies of the natural nisin variant, which has been designated nisin Z, confirmed the His27Asn substitution and idicated that it has a similar structure to nisin.
