Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe outer membrane lipoprotein of the Escherichia coli cell envelope has characteristic lipid modifications at an amino-terminal cysteine and can exist in a form bound covalently to the peptidoglycan through a carboxyl-terminal lysine. The 56-residue polypeptide moiety of the lipoprotein, designated Lpp-56, folds into a stable, trimeric helical structure in aqueous solution. The 1.9 A resolution crystal structure of Lpp-56 comprises a parallel three-stranded coiled coil including a novel alanine-zipper unit and two helix-capping motifs. The amino-terminal motif forms a hydrogen-bonding network anchoring an umbrella-shaped fold. The carboxyl-terminal motif uses puckering of the tyrosine side-chains as a unique docking arrangement in helix termination. The structure provides an explanation for assembly and insertion of the lipoprotein molecules into the outer membrane of gram-negative bacteria and suggests a molecular target for antibacterial drug discovery.
