How Does Metallothionein Function?


MTs function primarily through their ability to chelate heavy metals. The high cysteine content of MTs provides numerous thiol groups, which form strong bonds with metal ions. This chelation process helps in sequestering toxic metals away from critical cellular components. Additionally, MTs participate in the regulation of essential metal ions like zinc and copper, ensuring that these metals are available in precise amounts required for various enzymatic reactions.
