Crystallographic data for troponin C from turkey skeletal muscle

Crystals of troponin C from turkey skeletal muscle suitable for high resolution X-ray studies have been grown from a Ca2+-containing solution. These crystals diffract to at least 2.5 A resolution, and have space group P3(1)21 or P3(2)21 and the following cell dimensions: a = b = 66.6 A, c = 61.0 A, alpha = beta = 90 degrees, gamma = 120 degrees.
