Biophys. Acta 1216:55-64(1993). CC -!- FUNCTION: Metallothioneins have a high content of cysteine CC residues that bind various heavy metals. {ECO:0000250}. CC -!- DOMAIN: Class I metallothioneins contain 2 metal-binding domains: CC four divalent ions are chelated within cluster A of the alpha CC domain and are coordinated via cysteinyl thiolate bridges to 11 CC cysteine ligands. Cluster B, the corresponding region within the CC beta domain, can ligate three divalent ions to 9 cysteines. CC -!- SIMILARITY: Belongs to the metallothionein superfamily. Type 1 CC family. {ECO:0000305}.
