Dabblings in PyMOL

This is my first movie built from rendered molecular structures using PyMOL (created in Feb 2007)...and also really my first excursion into 3D protein structures generally. This was part of an assignment for my bioinformatics class (InBio 465) at BYU. I was a little frustrated with the poor documentation on PyMOL's movie scripting capabilities, so I wrote a script that calculated the frame-by-frame between zoom, translation, and rotation "key frames." First, I downloaded protein structure data from www.rcsb.org/pdb/ which looked cool (the POPE membrane I found elsewhere on the net, and I duplicated in twice to create the semi-continuous layer you see in the first scene). Using PyMOL's Python interface, I positioned molecules into key moments and used my script to generate a series of transitional frames, with an output png file made at each step. Finally, I added music and put all the frames together using VideoMach (not the greatest, but it was easy and fast). The scene where the structure attaches itself to the DNA helix is correct, as I took it directly from the PDB file. The heteroatom shooting off the MDM2/p53 complex is a complete falsification for effect. I didn't have any proteins I was intimately familiar with (yet...I'm still an undergrad), so I took some artistic license on that one. Enjoy. -Elliott
