Abstract:
The importance of the polymorphic-phase behavior of lipid A structural variations in determining their endotoxic activities has been recognized previously, but any potential role for lipid A polymorphism in controlling outer membrane structure and function has been largely ignored until now. In a recent article in mBio [7(5):e01532-16, https://doi.org/10.1128/mBio.01532-16], Katherine E. Bonnington and Meta J. Kuehn of Duke University's Department of Biochemistry make a compelling case for considering how the molecular shapes of the various lipid A structural subtypes found in the outer membrane contribute to the process of outer membrane vesicle (OMV) formation.
