PROTEINS WERE DIALYZED IN A BUFFER OF 10 MM TRIS-HCL, PH 8.5, 1 MM DTT. THE PROTEIN WAS CONCENTRATED TO 10 MG/ML USING AMICON ULTRAFREE CENTRIFUGAL FILTER DEVICES, AND INHIBITOR, AC-DEVD-CMK RECONSTITUTED IN DMSO, WAS THEN ADDED AT 5:1 WT:WT, INHIBITOR TO PEPTIDE. THE PROTEIN WAS DILUTED TO A CONCENTRATION OF 8 MG/ML BY ADDING 10 MM TRIS-HCL, PH 8.5, CONCENTRATED DTT AND CONCENTRATED NAN3 SO THAT THE FINAL BUFFER WAS 10 MM TRIS-HCL, PH 8.5, 10 MM DTT, 3 MM NAN3. 2 UL OF CONCENTRATED PROTEIN WAS MIXED 1:1 WITH WELL BUFFER THAT CONTAINED 100 MM SODIUM CITRATE, PH 5, 3 MM NAN3, 10 MM DTT AND 17% PEG 6000 W/V. SOLUTIONS WERE INCUBATED AT 18 DEG C USING THE HANGING DROP METHOD. CRYSTALS GREW WITHIN THREE DAYS FOR WILD- TYPE CASPASE-3 AND WITHIN TWO WEEKS FOR THE MUTANTS. |
