HUMAN INSULIN DISULFIDE ISOMER, NMR, 10 STRUCTURES
Contents |
Overview
We have determined the structure of a metastable disulphide isomer of, human insulin. Although not observed for proinsulin folding or, insulin-chain recombination, the isomer retains ordered secondary, structure and a compact hydrophobic core. Comparison with native insulin, reveals a global rearrangement in the orientation of A- and B-chains. One, face of the protein's surface is nevertheless in common between native and, non-native structures. This face contains receptor-binding determinants, rationalizing the partial biological activity of the isomer. Structures of, native and non-native disulphide isomers also define alternative, three-dimensional templates. Threading of insulin-like sequences provide, an experimental realization of the inverse protein-folding problem.
Disease
