A section of the electron-density map of the 170 kDa protein (see text) (a) based solely on MAD phasing information at 2.4 Å resolution and (b) after density modification and phase extension to 1.65 Å with the program DM (Collaborative Computational Project, Number 4, 1994). The figure was produced with the program BOBSCRIPT (Esnouf, 1997; Kraulis, 1991) |
