Figure 3
(a) Fitting of the [AsnB26]-insulin B26-turn-like structure (lilac) to the insulin–IR complex. The modelled native insulin B-chain is shown in white and the modified TyrB26 site is shown in red. The colour code is as in the other figures. (b) The B26-turn-like conformation poises the [AsnB26]-insulin B-chain to fulfil hydrophobic and hydrogen-bond (dashed lines) interactions with some key IR residues (O atoms in red, N atoms in blue). The hydrogen-bond capping of the Val713 CO group by the important Arg14 (that must be bypassed by the B27–B30 chain) is also indicated. |
