General annotation (Comments)

Function	This protein specifically catalyzes the removal of signal peptides from prolipoproteins By similarity. HAMAP-Rule MF_00161
Catalytic activity	Release of signal peptides from bacterial membrane prolipoproteins. Hydrolyzes -Xaa-Yaa-Zaa-|-(S,diacylglyceryl)Cys-, in which Xaa is hydrophobic (preferably Leu), and Yaa (Ala or Ser) and Zaa (Gly or Ala) have small, neutral side chains. HAMAP-Rule MF_00161
Pathway	Protein modification; lipoprotein biosynthesis (signal peptide cleavage). HAMAP-Rule MF_00161
Subcellular location	Cell membrane; Multi-pass membrane protein By similarity HAMAP-Rule MF_00161.
Sequence similarities	Belongs to the peptidase A8 family.
