SIRAS phasing of SsAT. (a) Progress of density modification, monitored by the protein–solvent contrast versus modification cycles, using SHELXE. (b) Selective region of electron density in the solvent-flattened map with experimental phases. (c) Electron-density map (2FoFc) of the same region in the model after automatic residue building in ARP/wARP. All maps are contoured at 1σ.
