title: Crystallization and preliminary X-ray analysis of the lactose-specific phosphocarrier protein IIAlac of the phosphoenolpyruvate: sugar phosphotransferase system from Staphylococcus aureus.
abstract: The IIA constituent of the lactose permease from Staphylococcus aureus has been crystallized in two different forms. Crystals of form I have been grown from polyethylene glycol 4000 with beta-octyl glucoside. They diffract to 3.0 A resolution and belong to space group C2 with unit cell dimensions a = 141.7 A, b = 130.7 A, c = 96.5 A and beta = 96.2 degrees. Form II crystals have been obtained from a solution containing polyethylene glycol 400, ammonium sulfate and manganese chloride. They diffract to at least 2.8 A resolution and belong to space group P2(1)2(1)2(1) with unit cell dimensions a = 89.9 A, b = 101.5 A and c = 90.9 A.
