CagZ is a 23 kDa protein consisting of a single compact L-shaped domain, composed of seven alpha-helices that run antiparallel to each other. 70% of the residues are in alpha-helix conformation and no beta-sheet is present. CagZ is essential for the translocation of the pathogenic protein CagA into host cells [1].	Domain
