Tyrosine modification increases the affinity of gastrin for ferric ions
The peptide hormone gastrin(17), which occurs naturally in both tyrosine sulphated and unsulphated forms, binds two ferric ions with pM affinities. The aim of this study was to investigate the hypothesis that sulphation or phosphorylation of gastrin(17) altered ferric ion binding, and/or affinity fo...
