New Enzymes in the Laboratory
A new paper in Nature this week from NAI’s NASA Ames Research Center Team describes a new technique they’ve developed through which completely new enzymes can be evolved in the laboratory. The process does not require prior understanding of how the enzymes will work, but uses product formation as the sole selection criterion.

Potential Origin of Primordial Protein Enzymes
Life on earth is facilitated by a multitude of enzymes that catalyze essential chemical reactions. The vast majority of today’s enzymes are proteins, yet looking at the complex and intricate structures of natural enzymes it is hard to imagine how the first enzymes emerged.
However, new experiments by Seelig and Szostak, show that small, simple enzymes can evolve rather easily. In the August 16, 2007 issue of Nature, they describe the generation of an...
