Use a Web-based interactive search engine to retrieve the user desired similar 3D structural fragments from a selected subset of 25 or 90% non-homologous protein chains.
Highlights:
The search is based on the comparison of the main chain backbone conformational angles.
Additionally, the queried motifs can be superimposed to find out how similar the structural fragments are, so that the information can be effectively used in molecular modeling.
The engine has facilities to view the resultant superposed or individual 3D structure(s) on the client machine.
