Part of the ESX-5 specialized secretion system, which is responsible for the secretion of EsxN and a number of PE_PGRS and PPE proteins, including PPE41 (PubMed:22340629, PubMed:22925462). EccA5 exhibits ATPase activity and may provide energy for the export of ESX-5 substrates (By similarity). Part of the ESX-5 / type VII secretion system (T7SS), which is composed of cytosolic and membrane components. Deletion mutant does not secrete EsxN and shows a minor reduction of PPE41 secretion. Belongs to the CbxX/CfxQ family.
