Crystal structure of MBP-PYD.

<p>(A) Cartoon representation of a crystallographic asymmetric unit containing two copies of the MBP-PYD fusion protein. The MBPs are colored in grey, and the PYDs in chains A and B, are colored in green and cyan, respectively. (B) MBP-PYD structure in chain A. The amino terminus is labeled by “N” and the Carboxyl terminus is labeled by “C”. The linker region is colored in wheat and shown in sticks. The maltose molecule bound to MBP is shown in spheres.
