Crystallization and preliminary X-ray diffraction studies of the Pseudomonas marginata esterase EstB

Crystals of the esterase EstB were obtained at 277 K with the hanging-drop technique from polyethylene glycol 4000 solutions containing 2-propanol at pH 7.5. The crystals belong to the trigonal space group P3₁21 (or P3₂21) with cell dimensions a = b = 82.9 and c = 193.4 Å (at 100 K). The crystals diffract beyond a resolution of 2.0 Å.
