FIGURE 3.

Crystal structure of PexRD54. A, schematic representation of the crystal structure of PexRD54 showing the five tandem WY domains (blue, magenta, yellow, coral, and cyan) and the disordered AIM motif at the C terminus (circles with single letter amino acid codes shown). The N and C termini are labeled. B, superimposition of the WY domains of AVR3a11 (top left, green) on the WY domains from PexRD54. The characteristic hydrophobic residues of each WY domain are also shown in stick representation. The PexRD54 WY domains are colored as in A.
