Cryo-EM structures of a LptDE transporter in complex with Pro-macrobodies offer insight into lipopolysaccharide translocation
Abstract
Lateral opening of the LptDE transporter in the outer membrane of Gram-negative bacteria is necessary for insertion of lipopolysaccharides. Here, Botte et al. report a cryo-EM structure of a partially opened LptDE transporter, in complex with rigid chaperones derived from nanobodies.
