CC -!- FUNCTION: Plays an important role in virulence (PubMed:15213144). A
CC highly abundant outer membrane lipoprotein that controls the distance
CC between the inner and outer membranes. The only protein known to be
CC covalently linked to the peptidoglycan network (PGN). Also non-
CC covalently binds the PGN. The link between the cell outer membrane and
CC PGN contributes to maintenance of the structural and functional
CC integrity of the cell envelope, and maintains the correct distance
CC between the PGN and the outer membrane (By similarity).
CC {ECO:0000255|HAMAP-Rule:MF_00843, ECO:0000269|PubMed:15213144}.
CC -!- SUBUNIT: Homotrimer. {ECO:0000255|HAMAP-Rule:MF_00843}.
CC -!- SUBCELLULAR LOCATION: Cell outer membrane {ECO:0000255|HAMAP-
CC Rule:MF_00843}; Lipid-anchor {ECO:0000255|HAMAP-Rule:MF_00843};
CC Periplasmic side {ECO:0000255|HAMAP-Rule:MF_00843}. Secreted, cell wall
CC {ECO:0000255|HAMAP-Rule:MF_00843}; Peptidoglycan-anchor
CC {ECO:0000255|HAMAP-Rule:MF_00843}. Note=Attached via its lipidated N-
CC terminus to the inner leaflet of the outer membrane. Attached to the
CC peptidoglycan network (PGN) via its C-terminus. {ECO:0000255|HAMAP-
CC Rule:MF_00843}.
CC -!- INDUCTION: This gene is probably poorly expressed.
CC {ECO:0000250|UniProtKB:E8XH69}.
CC -!- DISRUPTION PHENOTYPE: The integrity of the cell envelope in a lpp null
CC mutant (double-knockout) is not affected.
CC {ECO:0000269|PubMed:15213144}.
CC -!- SIMILARITY: Belongs to the Lpp family. {ECO:0000255|HAMAP-
CC Rule:MF_00843}.
