CC -!- FUNCTION: Modulates cellular lipopolysaccharide (LPS) levels by
CC regulating LpxC, which is involved in lipid A biosynthesis. May act by
CC modulating the proteolytic activity of FtsH towards LpxC. May also
CC coordinate assembly of proteins involved in LPS synthesis at the plasma
CC membrane. {ECO:0000256|HAMAP-Rule:MF_00994}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000256|HAMAP-
CC Rule:MF_00994}; Single-pass membrane protein {ECO:0000256|HAMAP-
CC Rule:MF_00994}; Cytoplasmic side {ECO:0000256|HAMAP-Rule:MF_00994}.
CC -!- SIMILARITY: Belongs to the LapB family. {ECO:0000256|HAMAP-
CC Rule:MF_00994}.
