Starting Model(s) Initial Refinement Model(s) Type Source Accession Code Details experimental model PDB 1AJV PDB ENTRY 1AJV
Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION 5.5 277 CRYSTALLIZATION WAS PERFORMED BY VAPOR DIFFUSION. PROTEASE (2 MG/ML) AND INHIBITOR (40 MM IN DMSO) WAS MIXED IN A RATIO OF 1:1 AND SUBJECTED TO COCRYSTALLIZATION. DROPS CONSISTING OF 5 MICROLITERS OF THE PROTEASE-INHIBITOR MIXTURE PLUS 5 MICROLITERS OF THE CRYSTALLIZATION BUFFER (50 MM MES PH 5.5, 0.4 M NACL AND 0.02% (W/V) NAN3) WERE EQUILIBRATED AGAINST THE SAME BUFFER AT 4 DEGREES C., vapor diffusion, temperature 277K
