Structure of an invertebrate metallothionein from Scylla serrata.

Abstract

and, furthermore, in contrast to the metal ion hetero- geneity (Zn2+ plus Cd) found in cadmium-induced vertebrate metallothioneins, the crab metallothionein contains only Cd. The '13Cd NMR spectrum of Cd2+- induced crab MT-1 shows five resolved multiplets in the chemical shift range of
