1VAPOR DIFFUSION, HANGING DROP2771 ul of SERCA1a at 15 mg/mL in 2% n-nonyl-beta-D-maltopyranoside (nonyl maltoside) (Anatrace), 20% glycerol, 100 mM MOPS (pH 7.0), 0.12 M sucrose, 80 mM KCl, 3 mM MgCl2, and 2.8 mM EGTA was mixed with 1 uL of phospholamban at 2.1 mg/mL in 20 mM MOPS (pH 7.2), 20% glycerol, and 0.1 % decyl maltoside or 0.01% dodecyl maltoside. This protein mixture was then added to an equal volume of crystallization liquor; 15 % glycerol, 17% (W/V) PEG-2000, 200mM NaOAc, and 5 mM beta-mercoptoethanol), VAPOR DIFFUSION, HANGING DROP, temperature 277K
