Abstract excerpt
Crystal structures of the ferric H93G myoglobin (Mb) cavity mutant containing either an anionic proximal thiolate sulfur donor or a carboxylate oxygen donor ligand are reported at 1.7 and 1.4 A resolution, respectively. The crystal structure and magnetic circular dichroism spectra of the H93G Mb beta-mercaptoethanol (BME) thiolate adduct reveal a high-spin, five-coordinate complex. Furthermore, the bound BME...
