Structure of Native HIV-1 Env trimer EMD 5021
Importing Cryo-electron microscopy (3DEM) data into Sketchfab
EMD-5021 (viral membrane), EMD-5019 (spike), and PDB 3DNN (fitted coordinates) were downloaded from the EMDataBank and RCSB Protein Databank, respectively. The model components were colored using Chimera’s interactive ribbon and volume gradient settings.
Once the model was imported into Sketchfab (SF), lighting and background color were adjusted. Annotation tag location and text were provided by Dr. Subramaniam (Laboratory of Cell Biology, Center for Cancer Research, National Cancer Institute, National Institutes of Health, Bethesda, MD 20892, USA).
The SF generated embed code was copied and pasted onto this page (see Fig. 1). Click the “Play” button to start the interactivity. Use the arrows located on the bottom of the viewer ( ) to navigate to the various positions!
Cryo-electron microscopy (3DEM) is a field of structural biology that deals with the determination of 3D structures of macromolecular complexes and cells. This emerging field helps to bridges the gap between cell biology and crystallography/NMR.
EMDataBank is the unified global portal for the deposition and retrieval of 3DEM density maps, atomic models and associated metadata.
In order to test if this type of data would import into Sketchfab (SF), various structures were downloaded from the above site. After conversion into acceptable 3d formats, the models were uploaded to SF and embedded on the page above.
