Contrary to what some scientists have suggested, key intracellular particles known as ribosomes serve as mechanical matchmakers or readout devices rather than acting chemically to speed up reactions in the body the way enzymes do, University of North Carolina at Chapel Hill researchers and colleagues have discovered. A report on the findings by Drs. Annette Sievers and Richard Wolfenden of the UNC School of Medicine appears in the new issue of the Proceedings of the National Academy of Sciences.Besides Sievers and Wolfenden, report authors are doctoral student Malte Beringer and Dr. Marina V. Rodnina of the University of Witten/Herdecke in Witten, Germany.
