| FUNCTION | This protein specifically catalyzes the removal of signal peptides from prolipoproteins. |
| CATALYTIC ACTIVITY | Reaction=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.; EC=3.4.23.36; |
| PATHWAY | Protein modification; lipoprotein biosynthesis (signal peptide cleavage). |
| case not defined <Property:Membrane> or <Property:Membrane=1> | |
| SUBCELLULAR LOCATION | Cell membrane; Multi-pass membrane protein. |
| else case <Property:Membrane=2> | |
| SUBCELLULAR LOCATION | Cell inner membrane; Multi-pass membrane protein. |
| end case | |
| SIMILARITY | Belongs to the peptidase A8 family. |
