<StructureSection load='2yxr' size='350' side='right' caption='Structure of preprotein translocase subunits SecY (grey), SecE (green), SecG (pink) (PDB entry 2yxr)' scene=>
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. For more details see SecA PBD motions.
