Both proteins show conserved near iron transporter (NEAT) domains (Pfam:PF05031) that function synergistically. These domains, essential for the arrest of iron, are appropriately positioned by an alpha-helical linker domain (this entry), which does not interact itself with the heme group. In IsdH, this linker domain forms a three-helix bundle structure that is essential for efficient heme capture [1-4].
