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
