Abstract
|
|
|
X-ray crystal structures of human serum transferrin (77 kDa) with Yb(III) or
Fe(III) bound to the C-lobe and malonate as the synergistic anion show that the
large Yb(III) ion causes the expansion of the metal binding pocket while
octahedral metal coordination geometry is preserved, an unusual geometry for a
lanthanide ion.
