Figure 2
P1 subsite. Shown are mFo OMIT electron-density maps contoured at 1σ for (a) the mAng–PO4 and (b) the mAng–SO4 structures. Also shown are potential hydrogen bonds (dashed lines) in the (c) mAng–PO4 (anion orientation A), (d) mAng–SO4, (e) mAng–PO4 (anion orientation B) and (f) hAng–PO4 (PDB code 1hby ; Leonidas et al., 2001  ) structures. Residues involved in anion coordination are labelled and highlighted with colours according to the following scheme: mAng carbon, gold; hAng carbon, grey; nitrogen, blue; oxygen, red. The P1 subsite of mAng–PO4 is occupied by phosphate ions in two orientations, A (purple) and B (green); adjacent orientation-specific water molecules are coloured likewise. Bound anions in the mAng–SO4 and hAng–PO4 structures are coloured orange and purple, respectively. The side chain of Arg5 is omitted for clarity. |
