Function

function

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

Caution

Lacks conserved residue(s) required for the propagation of feature annotation.
The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.

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.
    EC:3.4.23.36 (UniProtKB | ENZYME | Rhea)

Pathway

Protein modification; lipoprotein biosynthesis (signal peptide cleavage).
