The periplasmic chaperone network ensures the biogenesis of bacterial outer membrane proteins (OMPs) and has recently been identified as a promising target for antibiotics. SurA is the most important member of this network, both due to its genetic

Domain Interactions Determine the Conformational Ensemble of the Periplasmic Chaperone SurA

October 1, 2020
Dagan C. Marx, Mathis J. Leblanc, Ashlee M. Plummer, Susan T. Krueger, Karen G. Fleming
SurA is thought to be the most important periplasmic chaperone for outer membrane protein biogenesis. Its structure is composed of a core region and two peptidylprolyl isomerase domains, termed P1 and P2, connected by flexible linkers. As such these three
