PilZ is a c-di-GMP binding domain [3] found in widespread cytoplasmic receptors, which is involved in regulation of motility, biofilm formation and virulence of many bacterial pathogens. This domain binds c-di-GMP through RXXXR and [D/N]hSXXG motifs, however, some PilZ domains lack these motifs and do not bind c-di-GMP [6]. Proteins which contain PilZ are known to interact with the flagellar switch-complex proteins FliG and FliM. This interaction results in a reduction of torque generation and induces CCW motor bias [5]. This is the canonical PilZ domain whose structure consists of six beta-strands that form a beta barrel, followed by a long C-terminal alpha-helix [6].	Domain
