They have a high content of cysteine residues that bind the metal ions through clusters of thiolate bonds [, , ] species, including sea urchins, fungi, insects and cyanobacteria. Class III MTs are atypical polypeptides composed of gamma-glutamylcysteinyl units. This original classification system has been found to be limited, in the sense that it does not allow clear differentiation of patterns of structural similarities, either between or within classes. Consequently, all class I and class I MTs (the proteinaceous sequences) have now been grouped into families of phylogenetically-related and thus alignable sequences. Diptera (Drosophila, family 5) MTs are 40-43 residue proteins that contain 10 conserved cysteines arranged in five Cys-X-Cys groups. In particular, the consensus pattern C-G-x(2)-C-x-C-x(2)-Q-x(5)-C-x-C-x(2)-D-C-x-C has been found to be diagnostic of family 5 MTs. The protein is found primarily in the alimentary canal, and its induction is stimulated by ingestion of cadmium or copper []. Mercury, silver and zinc induce the protein to a lesser extent. Family 5 includes subfamilies: d1, d2. Only one d2 is known until now. Subfamilies hit the same entry.; GO: 0046872 metal ion binding

They have a high content of cysteine residues that bind the metal ions through clusters of thiolate bonds [, ]. An empirical classification into three classes has been proposed by Fowler and coworkers [] and Kojima []. Members of class I are defined to include polypeptides related in the positions of their cysteines to equine MT-1B, and include mammalian MTs as well as from crustaceans and molluscs. Class II groups MTs from a variety of species, including sea urchins, fungi, insects and cyanobacteria. Class III MTs are atypical polypeptides composed of gamma-glutamylcysteinyl units []. This original classification system has been found to be limited, in the sense that it does not allow clear differentiation of patterns of structural similarities, either between or within classes. Consequently, all class I and class II MTs (the proteinaceous sequences) have now been grouped into families of phylogenetically-related and thus alignable sequences. This system subdivides the MT superfamily into families, subfamilies, subgroups, and isolated isoforms and alleles. The metallothionein superfamily comprises all polypeptides that resemble equine renal metallothionein in several respects []: e.g., low molecular weight; high metal content; amino acid composition with high Cys and low aromatic residue content; unique sequence with characteristic distribution of cysteines, and spectroscopic manifestations indicative of metal thiolate clusters. A MT family subsumes MTs that share particular sequence-specific features and are thought to be evolutionarily related. The inclusion of a MT within a family presupposes that its amino acid sequence is alignable with that of all members. Fifteen MT families have been characterised, each family being identified by its number and its taxonomic range: e.g., Family 1: vertebrate MTs [see http://www.bioc.unizh.ch/mtpage/protali.html]. Echinoidea (sea urchin, family 4) MTs are 64-67 residue proteins. Members of this family are recognised by the sequence pattern P-D-x-K-C-[V,F]-C-C-x(5)-C-x-C-x(4)-C-C-x(4)-C-C-x(4,6)-C-C located near the N terminus. The taxonomic range of the members extends to sea urchins (echinodea). The protein sequence is divided into two structural domains, each containing 9 and 11 Cys residues binding 3 and 4 bivalent metal ions, respectively. Family 4 includes subfamilies: e1, e2, they are separate phylogenetic groups. This entry includes the sea urchin proteins, and related sequences from worms.; PDB: 1QJK_A 1QJL_A.
