CC   -!- FUNCTION: Involved in the assembly of lipopolysaccharide (LPS).
CC       Required for the translocation of LPS from the inner membrane to the
CC       outer membrane. May form a bridge between the inner membrane and the
CC       outer membrane, via interactions with LptC and LptD, thereby
CC       facilitating LPS transfer across the periplasm. {ECO:0000255|HAMAP-
CC       Rule:MF_01914}.
CC   -!- SUBUNIT: Component of the lipopolysaccharide transport and assembly
CC       complex. {ECO:0000255|HAMAP-Rule:MF_01914}.
CC   -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000255|HAMAP-Rule:MF_01914}.
CC   -!- SIMILARITY: Belongs to the LptA family. {ECO:0000255|HAMAP-
CC       Rule:MF_01914}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAN82400.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
