Dynamic duo: Biochemists describe cooperative halves of life-critical enzyme

Oft-repeated adages praise the virtue and added efficiency of cooperative effort: "Many hands make light work," "Together, we're greater than the sum of our parts" and the like. Utah State University biochemists and colleagues report a tenacious enzyme that uses a similar principle to break nitrogen's unrelenting bonds and convert the life-critical gas into ammonia to fuel the world's food supply.
