Function

function

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

Caution

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).
