Biotech's new invaluable tool

With the ability to splice themselves out of proteins and paste the two loose ends of the protein back together, inteins are proving to be an invaluable tool in biotechnology. Just 20 years since their discovery, inteins are already being used to purify, manipulate, and even create proteins that were difficult (or impossible) to build using traditional techniques. "It's a very fast moving field," said chemical biologist linkurl:Fran Perler;http://www.neb.com/nebecomm/researchScientist.asp?id=FPerler of New England Biolabs, which currently has an intein-based purification method on the market. "The technology is all based on being able to introduce interesting chemical modifications into proteins and study how these modifications change the protein." The first intein...
