Comparison of the Arg63 loop in the A and B chains in the 1.8 Å resolution RNAse S structure (PDB entry 1sar). (a) Overlay of the Arg63 loop region from the A chain (blue) and B chain (green), illustrating the rotameric difference of Arg63 between the chains. (b) Arg63 from the A chain with 2mFo − DFc density map. (c) Arg63 from chain B with 2mFo − DFc density map. All maps are contoured at 1σ. Images were generated using KiNG (Chen et al., 2009). |
