The coordination sphere of Zn in the catalytic center of HCA II with a bound AZM molecule in three alternative binding modes 1 (a), 2 (b) and 3 (c) after QM refinement of the PDB structure 3hs4
. The difference density around the key N1 atom of the sulfonamido group of AZM is contoured at the 3.5σ level. |
