CC   -!- FUNCTION: Together with LptE, is involved in the assembly of
CC       lipopolysaccharide (LPS) at the surface of the outer membrane.
CC       {ECO:0000255|HAMAP-Rule:MF_01411}.
CC   -!- SUBUNIT: Component of the lipopolysaccharide transport and assembly
CC       complex. Interacts with LptE and LptA. {ECO:0000255|HAMAP-
CC       Rule:MF_01411}.
CC   -!- SUBCELLULAR LOCATION: Cell outer membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01411}.
CC   -!- PTM: Contains two intramolecular disulfide bonds. {ECO:0000255|HAMAP-
CC       Rule:MF_01411}.
CC   -!- SIMILARITY: Belongs to the LptD family. {ECO:0000255|HAMAP-
CC       Rule:MF_01411}.
