Deskripsi

Seven lipopolysaccharide (LPS) transport proteins (LptBFGCADE) mediate the transport of LPS from the inner to the outer membrane of Gram-negative bacteria. Here the authors provide mechanistic insights into LPS recognition and transportation by determining the cryo-EM structures of the inner membrane complex LptB2FGC bound to either LPS or AMP-PNP.
