X-RAY DIFFRACTION
X-ray crystallization conditions
VAPOR DIFFUSION, SITTING DROP；pH 5.6；277 K；For crystallization, reservoir solutions were prepared by a Tecan robot and 200-nL crystallization drops were dispensed on 96x2-well MRC plates (Innovadyne) by a Cartesian (Genomic Solutions) nanodrop robot at the High-Throughput Crystallography Platform of the Barcelona Science Park. Best crystals appeared in a Bruker steady-temperature crystal farm at 4C with protein solution (10 mg/mL in 50mM AMPSO pH9.0) and 20% PEG 8000, 0.1M (NH4)2SO4, 0.01M MgCl2, 0.05M MES pH5.6 as reservoir solution. These conditions were efficiently scaled up to the microliter range with 24-well Cryschem crystallization dishes (Hampton Research). Crystals were cryo-protected with 16% PEG 8000, 20% glycerol, 0.1M (NH4)2SO4, 0.01M MgCl2, 0.05M MES pH5.6. , VAPOR DIFFUSION, SITTING DROP, temperature 277K

X-RAY DIFFRACTION
X-ray crystallization conditions
VAPOR DIFFUSION, SITTING DROP；293 K；Crystallization assays were set up following the sitting-drop vapor diffusion method at the joint IBMB/IRB Automated Crystallography Platform of Barcelona Science Park. A Tecan robot (Tecan Trading) was used to prepare reservoir solutions, and a Cartesian Microsys 4000 XL robot (Genomic Solutions) or a Phoenix nanodrop robot (Art Robbins Instruments) dispensed nanocrystallization drops on 96x2-well Swissci Polystyrene MRC Crystallization Plates (Molecular Dimensions). Plates were stored at 4 or 20 degrees in thermostatic crystal farms (Bruker AXS). The astacin-hFB complex only crystallized after incubating the inhibitor (at 7.5 mg/mL) with six-fold molar excess of the peptidase in 10 mM Tris-HCl, 140 mM sodium chloride, pH 6.8. Crystals were obtained at 20 degrees in 200 nL:100 nL drops with protein complex solution and 20 percent (w/v) polyethylene glycol 3,350, 0.2 M sodium tartrate dibasic as reservoir solution.
