| Abstract: | Two periplasmic binding proteins, HisJ and LAO, which are involved in histidine and arginine transport, respectively, have been crystallized. Preliminary X-ray diffraction studies of the HisJ and LAO crystals show that both belong to the orthorhombic space group P2(1)2(1)2(1) and have unit cell dimensions of a = 39.26 A, b = 66.17 A, c = 88.33 A and a = 36.08 A, b = 78.34 A, c = 102.02 A, respectively. Both HisJ and LAO crystals diffract beyond 2.0 A resolution. |
