PELDOR Spectroscopy Distance Fingerprinting of the Octameric Outer‐Membrane Protein Wza from <i>Escherichia coli</i>.

Abstract

Distance fingerprinting: Pulsed electron-electron double resonance spectroscopy (PELDOR) is applied to the octameric membrane protein complex Wza of E. coli. The data yielded a detailed distance fingerprint of its periplasmic region that compares favorably to the crystal structure. These results provide the foundation to study conformation changes from interaction with partner proteins.
