Figure 2
UrdA′P structures at cryogenic and room temperatures. (a) Cartoon representation of the superposition of the UrdA′P-RT (orange) and UrdA′P-cryo (purple; PDB entry 6t88) structures using the FAD domain and an enlargement of the active site. (b) Left: 2mFoDFc map contoured at 1σ. Right: mFo − DFc omit polder map for residues 410–412 and the sulfate and water molecules contoured at 3σ for the UrdA′P-RT structure with bound sulfate. (c) Left: 2mFoDFc map contoured at 1σ. Right: mFoDFc omit polder map shown for residues 410–412 and the sulfate and water molecules contoured at 3σ for the UrdA′P-cryo structure. Occupancies for each of the Arg411 alternatives are indicated by the percentage values given.
