General description

L-α-phosphatidylethanolamine (E. coli) is the abundant phospholipid of 70-80%, present in the inner membrane of E. coli. PE in E. coli possesses the potential to form non-bilayer structure.


E. coli PE may be used to study the physical states and thermodynamic properties extracted from E. coli.

Biochem/physiol Actions

L-α-phosphatidylethanolamine (E. coli) contributes to the cytoskeletal organization during cytokinesis. It also interacts with several membrane proteins such as lactose permease.

Phosphatidylethanolamine (PE) is a major membrane phospholipid that is mainly localized in the inner leaflet of the plasma membrane. We previously demonstrated that PE was exposed on the cell surface of the cleavage furrow during cytokinesis. Immobilization of cell surface...
