description | Recombinant Aspergillus nidulans isopenicillin N synthase was purified from an Escherichia coli expression system. The apoenzyme in the presence of saturating concentrations of MnCl2 could be crystallized by either macro- or microseeding, using the hanging drop vapor diffusion technique with polyethylene glycol 8000 as precipitant. The crystals (0.5-1.0 mm overall dimensions) diffract X-rays to at least 2.0 A resolution at synchrotrons and belong to space group P212121 with unit cell dimensions of a = 59.2 A, b = 127.0 A, and c = 139.6 A. The asymmetric unit contains one dimer, and the solvent content of the crystals is 60%. The crystals are radiation sensitive. |
