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

SecA protein binds to the plasma membrane where it interacts with proOmpA to support translocation of proOmpA through the membrane. SecA protein achieves this translocation, in association with SecY protein, in an ATP dependent manner [1,2]. This domain represents the N-terminal ATP-dependent helicase domain, which is related to the Pfam:PF00270 [3].	Domain
