POPEYE WOULD BE PROUD Remember how Popeye turns into human dynamite whenever he eats spinach? Well, the new word is that enzymes in spinach may reduce dynamite to a harmless bunch of chemicals. Manish M. Shah, a research scientist at the U.S. Department of Energy's Pacific Northwest National Laboratory in Richland, Wash., is using nitroreductase enzymes to neutralize the nitroaromatic compounds in explosives. Nitroreductase enzymes--which normally are involved in photosynthesis--are ubiquitous, but Shah buys commercial stocks extracted from spinach. He says the pocket of such enzymes is big enough and comparable enough to suit nitroaromatics, and to continue a virtually endless catalysis of their reduction. Currently, unwanted explosives are incinerated. "It's a huge challenge for the Department of Defense to deal with explosive stockpiles. There are 500,000...
