Figure 4
Stereoview ribbon diagram comparing the packing of the two DPI_HAc molecules in the asymmetric unit with the packing of two molecules at the dimer–dimer interface in the T6 insulin hexamer. The B chains of the DPI_HAc dimer (in blue) are superimposed upon the B chains of two adjacent molecules from two different dimers in the 2-Zn insulin hexamer (in red). The superposition was made by the alignment of only the left-hand B9–B19 α-helix in each pair of molecules so as to illustrate the different packing arrangements of the two pairs of molecules. This figure was produced using BobScript (Esnouf, 1997). |
