We imagine making products “not found in nature”—but even natural microbes make molecules that organic chemists would never dream of. Look at thisantitumor agent discovered from a filamentous soil bacterium, the kind of bacteria that give soil that new smell in the springtime (Science 297:1170). Those sets of three parallel lines are each triple bonds, within a nine-carbon ring. Who would even think to draw such a thing, let alone make it? To make it, the bacteria use modular enzymes, nanoscale assembly lines that condense one functional part after another. The original nanotechnology.
