Crystallographic and computational studies of the metal ion binding properties of parvalbumin
An astonishing number of important physiological processes are regulated by the small alkaline earth metal, calcium. Regulatory Ca2+-binding proteins must be able to distinguish Ca2+ ions in the presence of greater ...
Structure of tropomyosin at 7A resolution
The crystal structure of tropomyosin has been determined by X-ray diffraction analysis at 7A resolution. Tropomyosin is a 400A-long muscle regulatory protein that consists of two parallel 33,000 Dalton alpha helices wound ...
