Absence of long-range diffusion of OmpA in E. coliis not caused by its peptidoglycan binding domain

Abstract

OmpA exhibits an absence of long-range (> ~100 nm) diffusion in the OM that is not caused by its PG binding domain. Therefore, other mechanisms are needed to explain this observation, such as the presence of physical barriers in the OM, or strong interactions with other elements in the cell envelope.
