Streptavidin-biotin complexes

If you have a Java-capable web browser, the DisMol applet should appear below. If you don't, you may find this page rather boring. This is a big applet, so it may take one or two minutes to load into your browser (sorry for the delay).
If you see a molecule below, you can try rotating the molecule in various directions by dragging your mouse on the black background (be sure to hold down the mouse button while you do that). See the text window for other tricks.

See the DisMol home page for the software that was used to display the molecules.
