At Berkeley: Intelligently Designed Molecular Evolution

BERKELEY, CA — Evolutionary paths to new therapeutic drugs, as well as a wide assortment of other enzyme products, have been created through, of all things, intelligent design. A team of researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have developed a technique in which the evolution of an important class of proteins is steered towards a desired outcome.
The results of this study were reported in the February 22, 2006, on-line edition of the journal Nature.
While the researchers have not yet reached the point where they can design a promiscuous enzyme to make any kind of product they want, even one that does not occur in nature, this demonstration represents a significant step in that direction. The idea would be to one day be able to design an enzyme synthase that would evolve along a specific functional pathway to yield a desired molecular product, then introduce it into microbes for mass production. In addition to synthesizing therapeutic drugs, other possible applications would include flavors, fragrances and nutraceuticals.
