Listeria monocytogenes is an opportunistic, food-borne human and animal pathogen. Host cell invasion requires the action of the internalins A (InlA) and B (InlB), which are members of a family of listerial cell-surface proteins. Common to these proteins are three distinctive N-terminal domains that have been shown to direct host cell-specific invasion for InlA and InlB ...
