X-ray structure of the TPR domain of OGT and the basis of substrate recognition. The TPR domain of OGT forms a homodimer of right-handed super-helices. The dimer is maintained through mainly hydrophobic interactions. The concave surface of the super helix is lined with asparagine residues. Like the peptide-binding surface of importin alpha, this contiguous stretch of asparagines may allow OGT to interact with substrates. Click the image to the right to open a movie of a 360° rotation of the OGT homodimer about the homodimer interface.
