(a) Orthorhombic crystals of SsGDH belonging to space group P21212, grown from 0.1 M HEPES pH 6, 13%(w/v) PEG 4000, 8%(v/v) propan-2-ol, 20 mM MgCl2 with 3.5 mg ml−1 protein. (b) Optimized crystals diffracting to 1.8 Å; the largest crystal is approximately 0.3 × 0.1 × 0.1 mm in size. The black bars correspond to 0.1 mm. |
