S26 family signal peptidase

This is a family of membrane signal serine endopeptidases which function in the processing of newly-synthesised secreted proteins. Peptidase S26 removes the hydrophobic, N-terminal, signal peptides as proteins are translocated across membranes. The active site residues take the form of a catalytic dyad that is Ser, Lys in subfamily S26A; the Ser is the nucleophile in catalysis, and the Lys is the general base. (from Pfam)

S26 family signal peptidase

S26 family signal peptidase is a membrane-bound serine protease which frees proteins tethered to inner or mitochondrial membranes by cleaving off signal peptides during polypeptide translocation

signal peptidase I

This HMM represents signal peptidase I from most bacteria. Eukaryotic sequences are likely organellar. Several bacteria have multiple paralogs, but these represent isozymes of signal peptidase I. Virtually all known bacteria may be presumed to A related model finds a simlar protein in many archaea and a few bacteria, as well as a microsomal (endoplasmic reticulum) protein in eukaryotes.
