Structure, dynamics and function of the outer membrane protein A (OmpA) and influenza

Structure, dynamics and function of the outer membrane protein A (OmpA) and influenza hemagglutinin fusion domain in detergent micelles by solution NMR.

FEBS Lett. 2003 Nov 27;555(1):139-43

Authors: Tamm LK, Abildgaard F, Arora A, Blad H, Bushweller JH

Recent progress from our laboratories to determine structures of small membrane proteins (up to 20 kDa) in detergent micelles by solution nuclear magnetic resonance (NMR) is reviewed. NMR opens a new window to also study, for the first time, the dynamics of membrane proteins. We report on recent attempts to correlate dynamic measurements on OmpA with the ion channel function of this protein. We also summarize how NMR and spin-label electron paramagnetic resonance spectroscopy and selective mutagenesis can be combined to provide a structural basis towards understanding the mechanism of influenza hemagglutinin-mediated membrane fusion.
