Figure 6
Model and maps after re-refinement of PDB entry 7zkg using BUSTER and the re-merged deposited data. The 2mFo − DFc electron density is shown in blue at 1 r.m.s. and the F(early) − F(late) difference map is shown in green (positive) and red (negative) at 5 r.m.s.. The S-adenosylhomocysteine (SAH) cofactor is shown in a thicker ball-and-stick presentation than the protein. Several typical indications of radiation damage are visible on the protein (from left to right): CysA64, AspA156 and GluA36. The cofactor itself seems to have suffered radiation damage to the sulfur and carboxyl group at the cysteine end.
