Protein
Lipoprotein signal peptidase
Gene
lspA
Organism
Pseudomonas putida ND6
Status
Functioni
This protein specifically catalyzes the removal of signal peptides from prolipoproteins.UniRule annotationARBA annotation
Caution
Lacks conserved residue(s) required for the propagation of feature annotation.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 annotationARBA annotation EC:3.4.23.36
: lipoprotein biosynthesis (signal peptide cleavage) Pathwayi
This protein is involved in the pathway lipoprotein biosynthesis (signal peptide cleavage), which is part of Protein modification.UniRule annotationView all proteins of this organism that are known to be involved in the pathway lipoprotein biosynthesis (signal peptide cleavage) and in Protein modification.
