Functioni

This protein specifically catalyzes the removal of signal peptides from prolipoproteins.UniRule annotation

Catalytic activityi

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.UniRule annotation

Pathwayi: lipoprotein biosynthesis (signal peptide cleavage)

This protein is involved in the pathway lipoprotein biosynthesis (signal peptide cleavage), which is part of Protein modification.UniRule annotation
