Native crystals of DtHNL1 were obtained by mixing 0.5ul 4 mg/mL protein sample (in 10 mM Tris-HCl pH 8.0) with 1 ul reservoir solution (0.9 M NaNO3; Na2HPO4; (NH4)2SO4 mix, 0.1 M Tris-Bicine Buffer pH 8.5 and 30% (w/v) polyethylene glycol monomethyl ether 550 & polyethylene glycol 20k; Morpheus condition C9). Additionally, native crystals were also grown by mixing 1 ul 4 mg/mL protein sample (in 10 mM Tris-HCl pH 8.0) with 0.5ul reservoir solution (0.1 M 2-(4-(2-hydroxyethyl)-1-piperazinyl) ethanesulfonic acid pH 7.5 and 10% (w/v) polyethylene glycol; JSCG condition B4). SeMet-DtHNL1 crystals were obtained in 0.2 M sodium thiocyanate, 20% (w/v) polyethylene glycol 3350. A 1:1 ratio of protein and screening solutions was used, using protein concentration of 3 mg/mL (in 10 mM Tris-HCl pH 8.0). |
