Protection of proteins against fibrillation may be afforded by introduction of certain histidine substitutions into the protein, such that a pair of histidines are present with sufficient spacing as to allow the histidines to coordinate with zinc. In the case of insulin, introduction of histidine residue substitutions at residues A4 and A8 together or a histidine residue substitution at residue B1, provides increased resistance to fibrillation while maintaining at least a majority of the activity of the insulin analogue.
