abstract = {Metallothioneins are small cysteine-rich proteins believed
to play a role, among others, in the homeostasis of
essential metal ions such as Zn(II) and Cu(I). Recently, we
could show that wheat E(c)-1 is coordinating its six Zn(II)
ions in form of metal-thiolate clusters analogously to the
vertebrate metallothioneins. Specifically, two Zn(II) ions
are bound in the N-terminal and four in the C-terminal
domain. In the following, we will present evidence for the
relative independence of the two domains from each other
with respect to their metal ion binding abilities, and
uncover three intriguing peculiarities of the protein.
Firstly, one Zn(II) ion of the N-terminal domain is relative
resistant to complete replacement with Cd(II) indicating the
presence of a Zn(II)-binding site with increased stability.
Secondly, the C-terminal domain is able to coordinate an
additional fifth metal ion, though with reduced affinity,
which went undetected so far. Finally, reconstitution of
apoE(c)-1 with an excess of Zn(II) shows a certain amount of
sub-stoichiometrically metal-loaded species. The possible
relevance of these finding for the proposed biological
functions of wheat E(c)-1 will be discussed. In addition,
extended X-ray absorption fine structure (EXAFS)
measurements on both, the full-length and the truncated
protein, provide final evidence for His participation in
metal ion binding.},
