Figure 2
Diffraction from crystals of sSEMA4D. (a) Diffraction to 3.5 Å resolution yielding an initial native data set (space group P1; unit-cell parameters a ≃ 79, b ≃ 79, c ≃ 91 Å, α ≃ 85, β ≃ 76, γ ≃ 61°). (b) Improved diffraction to 2.7 Å resolution resulting from unexpected dehydration resulting from (unsuccessful) heavy-metal soaks (data set NAT; space group P1; unit-cell parameters a = 73.3, b = 74.9, c = 88.8 Å, α = 76.3, β = 73.1, γ = 63.9°). (c) Image number 1 obtained on BM14 at the ESRF from a SeMet sSEMA4D crystal on BM14 showing diffraction to 3.0 Å resolution (data sets PK1, REM and PK2; space group C2; unit-cell parameters a = 71.5, b = 127.1, c = 87.2 Å, β = 103.7°; top right of panel shows an enlarged area of the image). (d) Image number 2648 from the same crystal after a total exposure time of 44 h 8 min (top right of panel shows an enlarged area of the image). (e) High-resolution (2.0 Å) diffraction from a dehydrated crystal of native sSEMA4D (data set HIRES; space group P1; unit-cell parameters a = 73.3, b = 76.8, c = 89.4 Å, α = 77.4, β = 73.4, γ = 63.6°). |
