PspA can form large scaffolds in Escherichia coli

PspA can form large scaffolds in Escherichia coli. Standar, K., Mehner, D., Osadnik, H., Berthelmann, F., Hause, G., Lünsdorf, H., Brüser, T., Lunsdorf, H, & Bruser, T FEBS Lett, 582(25-26):3585–3589, 2008.

The phage shock protein A (PspA) of Escherichia coli stabilizes the cytoplasmic membrane under stress conditions. Here we demonstrate that PspA can form hollow spherical or prolate spheroidal particles of about 30-40nm diameter with a scaffold-like arrangement of protein subunits at the surface. The 'PspA-scaffold' is the basic structure that is common to all particles. The PspA-scaffold may be of fundamental importance, as it could allow PspA to stabilize the integrity of membranes through numerous contact points over a large surface area.
