This model 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 [Protein fate, Protein and peptide secretion and trafficking].
