Signal peptidase I.
based on mapping to UniProt P00803
Cleavage of hydrophobic, N-terminal signal or leader sequences from secreted and periplasmic proteins.
-!- Unaffected by inhibitors of most serine peptidases, but site-directed mutagenesis implicates a Ser/Lys catalytic dyad in activity. -!- Cleaves a single bond -Ala-|-Ala- in M13 phage procoat protein, producing free signal peptide and coat protein. -!- Eukaryote signal peptidases that may have somewhat different specificity are known from the endoplasmic reticulum membrane and mitochondrial inner membrane. -!- Belongs to peptidase family S26. -!- Formerly EC 3.4.99.36.
