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

This domain is found in Cellulose Synthase Subunit B (BscB) from Cereibacter sphaeroides and similar sequences predominantly found in bacteria. BscB, involved in bacterial cellulose biosynthesis, is organized into two periplasmic carbohydrate binding domains (CBD-1/2, Pfam:PF03170) and two alpha/beta-domains with similarity with a flavodoxin-fold (FD1 and FD2) [1]. This entry represents FD2.	Domain
