Notes
Metallothioneins occur in almost all organisms. They can regulate heavy metal concentrations by binding them. Organisms can produce metalollothioneins in response to the presence of heavy metals. However, when the amount of heavy metals exceeds what the metallothioneins can handle, the toxic effects of the contaminants will be manifested.[2]
