Novel mechanism for nisin resistance via proteolytic degradation of nisin by the nisin resistance protein NSR.
Nisin is a 34-residue antibacterial peptide produced by Lactococcus lactis that is active against a wide range of gram-positive bacteria. In non-nisin-producing L. lactis, nisin resistance could be conferred by a specific nisin resistance gene (nsr), which encodes a 35-kDa nisin resistance protein (NSR). However, the mechanism underlying NSR-mediated nisin resistance is poorly understood. Here ...

15 صفحه اولNisin resistance of Streptococcus bovis.
The growth of Streptococcus bovis JB1 was initially inhibited by nisin (1 microM), and nisin caused a more than 3-log decrease in viability. However, some of the cells survived, and these nisin-resistant cells grew as rapidly as untreated ones. To see if the nisin resistance was merely a selection, nisin-sensitive cells were obtained from agar plates lacking nisin. Results indicated that virtua...
