title: Preliminary X-ray studies on the GTP: AMP phosphotransferase from beef heart mitochondria.
abstract: Crystals of GTP: AMP phosphotransferase from beef heart mitochondria suitable for X-ray analysis have been grown. They belong to space group I4 with unit cell dimensions: a = b = 88.2 A, c = 147.8 A. The asymmetric unit contains two molecules each of Mr = 26,000. So far, two heavy-atom derivatives have been obtained.
