Figure 8 A schematic illustration of the packing of T[6] insulin
hexamers in the hydrated R3 structure as viewed along the
hexagonal c axis. Dashed lines denote the pseudo-twofold axes
within the hexamers and the approximate boundary of each dimer.
`A' and `B' label contact sites that contain five and six
surface residues, respectively, that form nine interhexamer
contacts of less than 3.4 Å, four of which are hydrogen bonds.
Not shown are the contacts that exist between hexamers related
by a translation along the c axis.
