Figure 7 The 1 -contoured [A]-weighted (2F[o] - F[c]) electron density in the central core of the T[6] insulin hexamer in the rhombohedral structure of the dehydrated crystal at 100 K. The view is along the crystallographic threefold axis. The C^atoms (CG) are labeled on those GluB13 residues which are incomplete owing to disordered carboxylate groups. Prepared with the programs XtalView (McRee, 1999[McRee, C. E. (1999). J. Struct. Biol. 125, 156-165.]) and Raster3D (Merritt & Bacon, 1997[Merritt, E. A. & Bacon, D. J. (1997). Methods Enzymol. 277, 505-524.]).
