CC -!- FUNCTION: A highly abundant outer membrane lipoprotein that controls
CC the distance between the inner and outer membranes. The only protein
CC known to be covalently linked to the peptidoglycan network (PGN). Also
CC non-covalently binds the PGN. The link between the cell outer membrane
CC and 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. {ECO:0000255|HAMAP-
CC Rule:MF_00843}.
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: Constitively expressed under many tested conditions.
CC {ECO:0000269|PubMed:24331466}.
CC -!- SIMILARITY: Belongs to the Lpp family. {ECO:0000255|HAMAP-
CC Rule:MF_00843}.
