Members of this family adopt a secondary structure consisting of an open-face beta/alpha sandwich, with four antiparallel beta-strands and two alpha-helices. They bind to a corresponding domain on CheY, with subsequent phosphorylation of the CheY Asp57 residue, and activation of CheY, which then affects flagellar rotation [1].	Domain
