The SecA ATPase is involved in the insertion and retraction of preproteins through the plasma membrane. This domain has been found to cross-link to preproteins, thought to indicate a role in preprotein binding. The pre-protein cross-linking domain is comprised of two sub domains that are inserted within the ATPase domain [1].	Domain
