NSR from <i>Streptococcus agalactiae</i> confers resistance against nisin and is encoded by a conserved <i>nsr</i> operon

22 Jul 2013

Abstract excerpt

Nisin is a lantibiotic produced by Lactococcus lactis (L. lactis), which is active against many Gram-positive bacteria. However, in various pathogenic and nonpathogenic bacteria, the presence of a nisin resistance protein (NSR) confers resistance against nisin. Here, we show that NSR from Streptococcus agalactiae (SaNSR) confers 20-fold resistance when expressed in L. lactis. We also show that SaNSR is encoded by...
