Maintenance of lipid asymmetry in the bacterial outer membrane (OM) is mediated by the OmpC-Mla system, but mechanistic details remain to be elucidated. Here, the authors show that electrostatic interactions, conformational dynamics, and membrane thinning may facilitate spontaneous retrograde phospholipid transfer at the OM.
