Vacuolating cytotoxin precursor, VacA of 1287 aas that forms a hexameric pore in the membranes of target cells after processing (Pyburn et al. 2016).  The 88 kDa secreted VacA protein, composed of an N-terminal p33 domain and a C-terminal p55 domain, assembles first into water-soluble oligomers before inserting into membranes.  Details for the insertion process are known (Pyburn et al. 2016).  The biology of VacAs has been reviewed (Foegeding et al. 2016).
