ProteinX
ProteinX is a molecular viewer that specializes in protein mutations and energy minimization of these mutations to find the lowest potential energy state to stabilize the protein's structure. It is the first freely available tool that offers high resolution 3D images in real-time, and uses simulated annealing to perform energy minimization on amino acid residues within seconds, instead of minutes like with other tools.
Download
Version 0.91 of ProteinX has been released. Download from here.
ProteinX requires Windows, DirectX 9.0c, and a 3D video card (Either a Geforce FX/6/7 series or a Radeon 9500-9800/X1800 or newer). Please read the Readme.txt included in the zip for more details and instructions on how to run ProteinX.
Tutorials
ProteinX uses a simple interface for a complex process, making it easy even for a novice user to learn how to use a molecular viewer. Here is a tutorial and a video to show what ProteinX can do, along with screenshots for each step:
