'''THE THREE-DIMENSIONAL STRUCTURE OF HUMAN [113CD7] METALLOTHIONEIN-2 IN SOLUTION DETERMINED BY NUCLEAR MAGNETIC RESONANCE SPECTROSCOPY'''<br />


==Overview==
==THE THREE-DIMENSIONAL STRUCTURE OF HUMAN [113CD7] METALLOTHIONEIN-2 IN SOLUTION DETERMINED BY NUCLEAR MAGNETIC RESONANCE SPECTROSCOPY==
The three-dimensional structure of human [113Cd7]metallothionein-2 was, determined by nuclear magnetic resonance spectroscopy in solution., Sequence-specific 1H resonance assignments were obtained using the, sequential assignment method. The input for the structure calculations, consisted of the metal-cysteine co-ordinative bonds identified with, heteronuclear correlation spectroscopy, 1H-1H distance constraints from, nuclear Overhauser enhancement spectroscopy, and spin-spin coupling, constants 3JHN alpha and 3J alpha beta. The molecule consists of two, domains, the beta-domain including amino acid residues 1 to 30 and three, metal ions, and the alpha-domain including residues 31 to 61 and four, metal ions. The nuclear magnetic resonance data present no evidence for a, preferred relative orientation of the two domains. The, polypeptide-to-metal co-ordinative bonds in human metallothionein-2 are, identical to those in the previously determined solution structures of rat, metallothionein-2 and rabbit metallothionein-2a, and the polypeptide, conformations in the three proteins are also closely similar.

== Function ==
[https://www.uniprot.org/uniprot/MT2_HUMAN MT2_HUMAN] Metallothioneins have a high content of cysteine residues that bind various heavy metals; these proteins are transcriptionally regulated by both heavy metals and glucocorticoids.

== Publication Abstract from PubMed ==
The three-dimensional structure of human [113Cd7]metallothionein-2 was determined by nuclear magnetic resonance spectroscopy in solution. Sequence-specific 1H resonance assignments were obtained using the sequential assignment method. The input for the structure calculations consisted of the metal-cysteine co-ordinative bonds identified with heteronuclear correlation spectroscopy, 1H-1H distance constraints from nuclear Overhauser enhancement spectroscopy, and spin-spin coupling constants 3JHN alpha and 3J alpha beta. The molecule consists of two domains, the beta-domain including amino acid residues 1 to 30 and three metal ions, and the alpha-domain including residues 31 to 61 and four metal ions. The nuclear magnetic resonance data present no evidence for a preferred relative orientation of the two domains. The polypeptide-to-metal co-ordinative bonds in human metallothionein-2 are identical to those in the previously determined solution structures of rat metallothionein-2 and rabbit metallothionein-2a, and the polypeptide conformations in the three proteins are also closely similar.
