General annotation (Comments)

Function

Metallothioneins have a high content of cysteine residues that bind various heavy metals By similarity.

Domain

Class I metallothioneins contain 2 metal-binding domains: four divalent ions are chelated within cluster A of the alpha domain and are coordinated via cysteinyl thiolate bridges to 11 cysteine ligands. Cluster B, the corresponding region within the beta domain, can ligate three divalent ions to 9 cysteines.

Sequence similarities

Belongs to the metallothionein superfamily. Type 1 family.
