Where the fat’s at

In real estate, location is everything. The same might be said of lipids — those crucial cellular fats and oils that serve as building blocks for cells and as key energy sources for the body.

Engineered Proteins Will Lead to ‘Synthetic Biology’

Biochemists have developed a computational method to design proteins that can specifically detect a wide array of chemicals from TNT to brain chemicals involved in neurological disorders. In a paper in the May 8, 2003, issue of the journal Nature, they demonstrate the breadth of their design method, and also that such sensor proteins can be re-incorporated into cells to activate cellular signaling and genetic pathways.
