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}.
