A current model for protein secretion by prokaryotes

Description
The new polypeptide chain (the pro-protein) complexes with SecB, which prevents complete folding during transport to the membrane.

At the membrane an ATPase, SecA, drives translocation through the membrane with the aid of SecYEG, which forms a membrane pore.

The leader sequence is then cleaved off the secreted protein by a membrane peptidase.
