Figure 5
Modelling of SCM-SAH into YecO. The re-refined coordinates with either (a) the originally modelled Se-substituted SAH and Cl- ion or (b) remodelled SCM-SAH are displayed along with the 2mFo - DFc electron-density maps contoured at 1[sigma] and the mFo - DFc difference electron-density maps contoured at 3[sigma]. SCM-SAH is depicted with C atoms in cyan, while C atoms of protein residues are shown in green.  [article HTML]
