Figure 4
(a) Quaternary structure of the hCHAD dimer. The surface representation shows the lack of contacts between the subunits in the central part of the interface and the two interfaces formed between the respective N-terminal caps and repeats 4–9. (b) Key interactions within the dimer interfaces include ring stacking between His28 and Phe150 as well as hydrogen bonding between tyrosines and histidines. (c) Comparison of hCHAD and decorin (PDB entry 1xcd) dimers. Two monomers are superimposed (ribbon representation); the dashed line indicates an angle of 0°.
