sitting drop vapor difffusion from a solution containing 2 M ammonium sulfate, 4% polyethylene glycol 400, 100 mM Hepes, pH 7.5, drops consist of 0.004 ml of 20 mg/ml protein solution and 0.006 ml reservoir solution equilibrated against 0.05 ml of reservoir solution, crystals diffract to 1.75 A
structure at 2.1 A resolution. The catalytic Fe(III) is pentacoordinated by the conserved Tyr160, Tyr194, His218 and His220 residues, the citrate anion and one water molecule. Asp80, Thr81 and Val248 are responsible for the substrate specificity. The N-terminal domain is required for its soluble expression and enzyme catalysis
