The activity of
B in Listeria
monocytogenes is stimulated by high osmolarity and is necessary
for efficient uptake of osmoprotectants. Here we demonstrate that,
during cold shock,
B contributes to adaptation in a
growth phase-dependent manner and is necessary for efficient
accumulation of betaine and carnitine as cryoprotectants.
