Protein: ESX-1 secretion system protein EccA1 (ESX conserved component A1) (Type VII secretion system protein EccA1) (T7SS protein EccA1) (P9WPH9)
Organism: Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
Function: Part of the ESX-1 specialized secretion system, which delivers several virulence factors to host cells during infection, including the key virulence factors EsxA (ESAT-6) and EsxB (CFP-10). EccA1 exhibits ATPase activity and may provide energy for the export of ESX-1 substrates.
Subcellular location: Cytoplasm {ECO:0000305}.
