FERRIC-BINDING PROTEIN FROM HAEMOPHILUS INFLUENZAE
Overview
The first crystal structure of the iron-transporter ferric ion-binding, protein from Haemophilus influenzae (hFBP), at 1.6 A resolution, reveals, the structural basis for iron uptake and transport required by several, important bacterial pathogens. Paradoxically, although hFBP belongs to a, protein superfamily which includes human transferrin, iron binding in hFBP, and transferrin appears to have developed independently by convergent, evolution. Structural comparison of hFBP with other prokaryotic, periplasmic transport proteins and the eukaryotic transferrins suggests, that these proteins are related by divergent evolution from an, anion-binding common ancestor, not from an iron-binding ancestor. The iron, binding site of hFBP incorporates a water and an exogenous phosphate ion, as iron ... [(full description)]
