| Abstract: | There are 12 histidine residues/molecule in the iron-uptake regulation protein (Fur). Here we examine their pH dependence using proton nuclear magnetic resonance spectroscopy. The histidines have widely spread acid dissociation constants but we can not offer a simple explantation for their complicated behaviour. |
