Molecules are three-dimensional entities and stereo-vision of images on paper and on the screen is one of the most powerful, intuitive ways to appreciate that. We have practiced stero-vision in this course; here are a number of situations that require spatial awareness.

   

2002

This divergent stereo-view shows a trace of connected Cα atoms of a protein domain (the VH domain of the anti-Fluorescein antibody 4-4-20, 4FAB.PDB) and a wireframe representation of all its tryptophan sidechains.


Write down the label of the tryptophan that is a conserved element of the hydrophobic core of this domain.

2002

This divergent stereo-view shows a trace of connected Cα atoms of a Pleckstrin PH domain, 1PLS.PDB


Trace the backbone from the N-terminus to amino acid 52 with pencil or pen in one of the images.

I wouldn't ask this type of question any more - the drawing task seems a bit convoluted for the actual skill it is supposed to test.
