LTF is a bilobal protein with the N-terminal half and the C-terminal half called N-lobe and C-lobe. LTF binds with high affinity Fe+3 ion and an anion in both its N-lobe and its C-lobe<ref>PMID:8703903</ref>. The binding site is between the 2 domains of each lobe. The anion binds the Fe+3 in a 1,2 bidendate fashion.
