The structure of [113Cd(7)]-metallothionein (MT_nc) of the Antarctic fish, Notothenia coriiceps, the first three-dimensional structure of a fish, metallothionein, was determined by homonuclear 1H NMR experiments and, heteronuclear [1H, 113Cd]-correlation spectroscopy. MT_nc is composed of, an N-terminal beta domain with 9 cysteines and 3 metal ions and a, carboxy-terminal alpha-domain with 11 cysteines and 4 metal ions. The, position of the ninth Cys of the alpha domain of MT_nc is different from, the corresponding Cys of mammalian MTs. As a result, the last CXCC motif, in the mammalian MT sequence becomes CXXXCC in the fish MT. This, difference leads to a structural change of the alpha domain and, in turn, to a different charge distribution with respect to that observed in, mammalian metallothioneins.

== Publication Abstract from PubMed ==
 +
The structure of [113Cd(7)]-metallothionein (MT_nc) of the Antarctic fish Notothenia coriiceps, the first three-dimensional structure of a fish metallothionein, was determined by homonuclear 1H NMR experiments and heteronuclear [1H, 113Cd]-correlation spectroscopy. MT_nc is composed of an N-terminal beta domain with 9 cysteines and 3 metal ions and a carboxy-terminal alpha-domain with 11 cysteines and 4 metal ions. The position of the ninth Cys of the alpha domain of MT_nc is different from the corresponding Cys of mammalian MTs. As a result, the last CXCC motif in the mammalian MT sequence becomes CXXXCC in the fish MT. This difference leads to a structural change of the alpha domain and, in turn, to a different charge distribution with respect to that observed in mammalian metallothioneins.
