Structure of Panulirus interruptus hemocyanin at 5 Å resolution

The hemocyanin from the spiny lobster Panulirus interruptus, a hexamer with a molecular weight of approximately 540,000, was crystallized in space group P21 with two molecules in the unit cell and cell dimensions a = 119.8 Å, b = 193.1 Å, c = 122.2 Å and β = 118.1 °. With screened precession photographs a three-dimensional set of reflections was collected up to 10 Å resolution. Both the conventional and the fast rotation function programs...
