A 3-D SMID interaction. The x-ray crystallographic structure of Erwinia chrysanthemi L-Asparaginase associating with D-Aspartate (PDB ID: 1HG1), as viewed by Cn3D. The structure was annotated by SMID to highlight the domain residues (purple), domain residues contacting the D-Aspartate molecule (green) and the non-domain residues (grey). The D-Aspartate small molecule ligand is shown in space-fill format. The sequence/alignment viewer provides sequences for all chains found in the PDB record. For the sequence involved in the small molecule interaction, residues are colour-coded using the same scheme seen in the structural model.
