Figure 7
B-repeat residues forming the crystal contact to the IR region may belong to a `sticky patch' in the hydrophobic groove between strand β2 and the following loop (both coloured yellow in the cartoon). The B repeat of InlB392_T332E (PDB entry 7nms) is shown in cartoon representation with a transparent surface. The surface is coloured according to element, with C atoms in dark grey, N atoms in blue and O atoms in red. Residues involved in formation of the crystal contact with the IR region in InlB392_T332E (PDB entry 7nms) are shown in lighter colours with C atoms in white, N atoms in cyan and O atoms in pink. The white patch highlights the apolar nature of the groove between strand β2 and the following loop. |
