 == Function ==
-'''Preprotein translocase''' (PPT) is responsible for the recognition and membrane translocation of preproteins.  PPT contains receptors and import motor.  The translocase pathway contains a chaperone protein – '''SecB'''; an integral membrane complex – '''SecY, SecE, SecG;''' proteins promoting the release of the mature peptide into the periplasm – '''SecD, SecF'''; and ATPase unit - '''SecA'''<ref>PMID:9489663</ref>.
