(a) Diffraction image recorded at 42 kGy. (b) Background profile of the diffraction image shown in (a). (c) Stick model refined at 1.7 Å resolution using 9000 images of L42k-2 together with a 2mFo − DFc electron-density map contoured at 1.5σ (sky blue). O, N and S atoms in the model are shown in red, blue and yellow, respectively. |
