Project context and summary :

Listeriolysin S (LLS) is a bacteriocin from Listeria monocytogenes that targets other Gram-positive bacteria, including Listeria monocytogenes itself. In order to understand the mechanism of action of LLS on target bacteria, we exposed the LLS-susceptible L. monocytogenes strain 10430S to the bacteriocin. We identified the proteome of the target bacteria with the goal of understanding which metabolic pathways are upregulated upon exposure to LLS.
