Abstract

Histidine-binding protein, purified from periplasmic space of Escherichia coli K12, has been crystallized in a form suitable for X-ray analysis. Crystals of average size 0.3 mm x 0.15 mm x 0.15 mm have been grown by the hanging-drop method, with ammonium sulfate as precipitant. The space group if I4(1)22, with the unit cell dimensions a = b = 119.1 A; c = 151.8 A; Vm = 2.7 A3/dalton. There appear to be two protein subunits of molecular weight 25,000 each in the asymmetric unit.
