mFo − DFc polder OMIT maps contoured at 3.0σ for selected 9Hyp/ANS ligands. (a) The mysterious electron-density patch at site V(7) tentatively interpreted as MEL but ultimately marked with five water molecules (red spheres). (b) ANS at site P(1) with good definition in the electron density. (c) A poorly defined ANS molecule at S(2). (d) The single HEPES molecule at site P(7). |
