Bordetella bronchiseptica PagP is a Bvg-regulated lipid A palmitoyl transferase that is required for persistent colonization of the mouse respiratory tract.

Bordetella bronchiseptica lipopolysaccharide (LPS) expression varies depending on growth conditions, regulated by the Bvg system. A B. bronchiseptica pagP homologue was identified that is required for Bvg-mediated modification of the lipid A core region of LPS that occurs on switching from the Bvg- to the Bvg+ phase.
