Iron(III) complex of a trihydroxamate ligand with an Ala-Ala-(HO)Gly-Ala sequence as a model for ferrioxamines. Formation of well-defined peptide loop structure

Article abstract of DOI:10.1246/cl.1996.915

A dodecapeptide trihydroxamate ligand forms a well-defined chiral complex with iron(III) in which this small linear peptide assumes a unique loop conformation, uncommon to protein structures. The complex exhibits siderophore activity for a test microorganism.
