Figure 3. The CheZ[200-214] peptide-CheY interface. Ribbon representation of (a) the F432YZ[200-214] interface and (b) the P2(1)2(1)2YZ[200-214] interface. The side-chains of key contacting residues are illustrated as ball and stick models and hydrophobic contacts are shown as green patches. (c) Relative B-factors of CheZ[200-214] in the CheY-CheZ[200-214] structures. The relative B-factor versus CheZ residue number plot in Click to view the MathML source- [0?wchp=dGLbVlb-zSkzk] -free F432YZ[200-214] is shown in cyan, that in Click to view the MathML source- [0?wchp=dGLbVlb-zSkzk] -bound F432YZ[200-214] in deep blue and that in Click to view the MathML source- [0?wchp=dGLbVlb-zSkzk] -bound P2(1)2(1)2YZ[200-214] in orange. B[residue] is the overall B-factor for each residue and B[CheZ] is the overall B-factor for all atoms of CheZ[200-214] included in the final model. (d) Schematic representation of the CheY-CheZ[200-214] contacts. The F432Z[200-214] primary sequence in cyan and the P2(1)2(1)2Z[200-214] primary sequence in orange are shown on either side of the C-terminal half of CheY, represented in secondary structural elements. Participating residues are highlighted. Hydrophobic contacts are illustrated as continuous grey lines, salt bridges as broken black lines and hydrogen bonds as continuous black lines. The Click to view the MathML source- [0?wchp=dGLbVlb-zSkzk] -free and Click to view the MathML source- [0?wchp=dGLbVlb-zSkzk] -bound F432YZ[200-214] structures solved from crystals grown in Tris (pH 8.4) are used as representatives of F432YZ[200-214] structures in this Figure.
