Abstract excerpt

Nisin resistance development is one of food safety challenges posed by Listeria monocytogenes, an important foodborne pathogen that causes human listeriosis. The GtcA flippase enzyme is functionally crucial in two separate pathways that glycosylate cell envelope wall teichoic acids (WTA) with N-acetylglucosamine (NAG) and lipoteichoic acids (LTA) with galactose, respectively. This study investigated phenotypic...
