The K133R mutant of OSBS was concentrated to 15 mg/ml, dialyzed
against 5 mM Tris pH 8.3 containing 2 mM MgCl2, drop frozen as small
pellets in liquid nitrogen and stored at -80 C. Crystals were grown
at 20 C by small-scale batch experiments by combining 15 ml of protein
solution and 15 ml of a solution containing 12-13% MePEG 5000, 100 mM
sodium acetate, 60 mM MgCl2, at pH 5.5. SHCHC was included in the
crystallization at a final concentration of approximately 2.5 mM., microbatch, temperature 293K |
