Incompatibility of the P2(1)2(1)2mode of CheZ200-214 peptide binding in the F432 lattice. CheY molecules in P2(1)2(1)2YZ200-214, (CheY shown in wheat and CheZ200-214 shown in orange) are superimposed on the symmetry-related CheY molecules in F432YZ200-214 (CheY shown in gray and CheZ200-214 shown in cyan) in the F432 lattice. The BeF3−-free F432YZ200-214 structure solved from a crystal grown in Tris (pH 8.4) is used as a representative of all F432YZ200-214 structures in this figure.
