What is the fastest protein structure alignment?

Question

[rayoub]

As the title suggest, I would like to know what is the fastest pairwise protein structure alignment tool available that still manages to be accurate. The best I know of currently is CE.

I can’t speak to speed, but you might be interested in TM-align. It performs well for global, accurate, structure alignment.

The fastest won't be the most accurate. Define your metrics, how much accuracy is necessary?
