Function
Preprotein translocase (PPT) is responsible for the recognition and membrane translocation of preproteins. PPT contains receptors and import motor[1]. The translocase pathway contains:
- SecB - a chaperone protein
- SecY, SecE, SecG an integral membrane complex
- SecD, SecF - proteins promoting the release of the mature peptide into the periplasm
- SecA - an ATPase unit.
