CC -!- FUNCTION: This protein specifically catalyzes the removal of signal
CC peptides from prolipoproteins. {ECO:0000256|HAMAP-Rule:MF_00161,
CC ECO:0000256|RuleBase:RU000594}.
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:0000256|HAMAP-Rule:MF_00161,
CC ECO:0000256|RuleBase:RU000594};
CC -!- PATHWAY: Protein modification; lipoprotein biosynthesis (signal peptide
CC cleavage). {ECO:0000256|HAMAP-Rule:MF_00161}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|HAMAP-Rule:MF_00161};
CC Multi-pass membrane protein {ECO:0000256|HAMAP-Rule:MF_00161}.
CC -!- SIMILARITY: Belongs to the peptidase A8 family.
CC {ECO:0000256|ARBA:ARBA00006139, ECO:0000256|HAMAP-Rule:MF_00161,
CC ECO:0000256|RuleBase:RU004181}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00161}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
