The secondary structure elements are numbered according to the AVR2 structure. The residues mutated in this study (AVR2, Ile-109; AVR4, Lys-109; AVR6, Cys-58) are coloured green. Residue Cys-122 in AVR4, which was mutated to serine in a previous study [36], is indicated in blue. (B) Two tetramers found in the asymmetric unit of the AVR2-b crystal. (C) Monomer A of AVR2-b. The weighted difference – electron density map (blue), calculated in the absence of biotin, is drawn with a 1.5 Å radius around the atoms of D-biotin of the final structure of AVR2-b. Contours are shown at 3.0σ. The secondary structure elements of AVR2-b are numbered. (D) A close-up view of (C) focused on biotin.
