CC   -!- FUNCTION: This protein specifically catalyzes the removal of signal
CC       peptides from prolipoproteins. {ECO:0000255|HAMAP-Rule:MF_00161}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Release of signal peptides from bacterial membrane
CC         prolipoproteins. Hydrolyzes -Xaa-Yaa-Zaa-|-(S,diacylglyceryl)Cys-, in
CC         which Xaa is hydrophobic (preferably Leu), and Yaa (Ala or Ser) and
CC         Zaa (Gly or Ala) have small, neutral side chains.; EC=3.4.23.36;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00161};
CC   -!- PATHWAY: Protein modification; lipoprotein biosynthesis (signal peptide
CC       cleavage). {ECO:0000255|HAMAP-Rule:MF_00161}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00161}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00161}.
CC   -!- SIMILARITY: Belongs to the peptidase A8 family. {ECO:0000255|HAMAP-
CC       Rule:MF_00161}.
