The following links allow you to download structure files for some of the models used to generate the figures and diagrams used in my teaching and research. They are all in Brookhaven Protein Data Bank (PDB) format and can thus be used by graphical display applications such as RasMol. In addition to the versions of RasMol for Unix, PCs and Macs, those of you who are users of Acorn computers (such as myself!) can obtain an excellent port of RasMol for Acorn's RiscOS operating system.
Please note that these structures are computer generated models which have been constructed from data of crystal structures obtained from the Brookhaven Protein Databank. I have found the models to be of use in my teaching and lecturing. It should be noted that these models have not necessarily been subjected to rigorous checking and are supplied as is.
This is a model of human IgG1 showing functional sites and has been published in the review Clark, M (1997), Chemical Immunology 65, 88-110 Antibody Engineering IgG Effector Mechanisms. The PDB format file used to generate this image is available for you to download from here.
An alternative model of IgG1 produced by Eduardo A. Padlan of the National Institutes of Health, Bethesda MD USA and described in Anatomy of the Antibody Molecule by Eduardo A. Padlan, Mol. Immunol. 31:169-217, (1994) is available for download from another site.
