Starting Model(s) Initial Refinement Model(s) Type Source Accession Code Details experimental model PDB 1S9J
Crystallization Crystalization Experiments ID Method pH Temperature Details 1 VAPOR DIFFUSION, HANGING DROP 6.9 291 The protein was concentrated to 15mg/m1 and incubated with 10 fold molar excess inhibitor plus 1mM MgAMP-PNP before crystallization. MEK1 crystals grew from hanging drop vapor diffusion using 12% w/v PEG 8000, 0.4M NH4H2PO4 and 0.1M HEPES pH 6.9 at 18 degC
