Beta-lactam sensitivity of Listeria monocytogenes.

ABSTRACT: While seven penicillin-binding proteins (PBPs) or PBP-like proteins
have been identified either by radiolabelled penicillin binding studies or
genomic analysis, only PBP3 has been considered of interest for Beta-lactams
activity against Listeria monocytogenes. Herein we reveal that both PBP4 and
Lmo0441 (a PBP-like protein) play a direct role in cephalosporin activity in L.
monocytogenes while PBP4 additionally has a protective affect against both
penicillin and carbapenem.
