Experimental electron-density maps of TβRII phased with HgCl2 derivatives. (a) A region of the MAD-phased electron-density map contoured at 1σ with the corresponding refined model. (b) SIRAS map produced by a 10 min quick-soak. (c) SIRAS map resulting from the long 12 h soak (taken from Sun & Radaev, 2002). |
