LPS-assembly lipoprotein LptE

Gene

lptE

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Together with LptD, is involved in the assembly of lipopolysaccharide (LPS) at the surface of the outer membrane. Required for the proper assembly of LptD. Binds LPS and may serve as the LPS recognition site at the outer membrane.UniRule annotation3 Publications

Interactioni

Subunit structurei

Component of the lipopolysaccharide transport and assembly complex. Interacts with LptD. May interact with LptD during its assembly by the beta-barrel assembly machine. Directly contacts LptD at a wide range of positions, encompassing multiple surfaces of LptE. In one specific interaction, LptE contacts a predicted extracellular loop of LptD through the lumen of the beta-barrel. This specific interaction is required for proper folding of LptD and assembly of the complex.UniRule annotation4 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
