hanging-drop vapour-diffusion technique, crystals diffract beyond 2.0 A resolution and belong to one of the orthorhombic space groups 12(1)2(1)2 or I222, with the unit-cell parameters a = 62.9, b = 125.4 and c = 137.0 A
structure solved by the single isomorphous replacement method including anomalous scattering to 2.0 A resolution. The enzyme folds into a large right-handed parallel beta helix, with a core composed of 13 turns of b strands. Four parallel beta sheets (PB1, PB1a, PB2 and PB3), formed by the consecutive turns, are typically separated by a residue in the conformation of a left-handed a helix
