1	VAPOR DIFFUSION, HANGING DROP	6.5	277	F33Y-CuBMb (1.0 mM) in 100 mM tris pH 8, (pH adjusted H2SO4), was mixed 1:3 with well buffer (0.1 M sodium cacodylate pH 6.5, 0.2 M sodium acetate trihydrate with 30% w/v polyethylene glycol 8000) using the hanging drop method with 300 uL well buffer in the well of the crystallization tray. Crystals obtained by this method were soaked with 10 eq CuSO4 in a mixture of E-F33Y CuBMb and well buffer consistent with the original drop conditions to avoid dissolving the crystals and subsequently with 15eq potassium cyanide, in a mixture of E-F33Y-CuBMb and well buffer using pH 7.0 sodium cacodylate, VAPOR DIFFUSION, HANGING DROP, temperature 277K
