Crystals and structures of CheY-CheZ200-214 complex. (a) Crystal morphologies of F432YZ200-214 (top two panels) and P2(1)2(1)2YZ200-214 (bottom two panels). (b) Structure of BeF3−-free F432YZ200-214 solved from a crystal grown in Tris (pH 8.4). (c) Structure of BeF3−-bound P2(1)2(1)2YZ200-214. (d) Structure of BeF3−-bound F432YZ200-214 solved from a crystal grown in Tris (pH 8.4). CheY molecules in the F432YZ200-214 structures ((b) and (d)) are shown in gray and that in the P2(1)2(1)2YZ200-214 structure ((c)) is shown in wheat. The CheZ200-214 peptide molecules in BeF3−-free F432YZ200-214 are shown in cyan ((b)), in BeF3−-bound P2(1)2(1)2YZ200-214, in orange ((c)) and in BeF3−-bound F432YZ200-214, in deep blue ((d)). Active-site water molecules are shown in deep red, Mg2+ ions are shown in magenta and BeF3− complexes are shown in yellow and the side chains of key active-site and switch residues are depicted in ball and stick models.
