is a 80 KDa bilobal, iron binding glycoprotein. In Apo transferrin (iron free form), N-lobe (brown) and C-lobe (green) bind to one ferric ion each to keep ferric ion in solution or transport to iron requiring cells
Both at the N-lobe and C-lobe specific amino acid residues are involved in binding to ferric ion. At the binding site of C-lobe so and so residues are involved in trapping iron. The amino acids involved in trapping of iron at the bind site of N-lobe includes. N lobe and C lobe undergoes a large conformational change upon binding to ferric ion.
