Introduction

Background

Metallothionein (MT) is a class of small metal-binding proteins that exists in bacteria, plants and animals. These proteins depending on their amino acid compositions have a high binding affinity with different bivalent metal ions. Once MT detects the corresponding metal, it binds the goal through covalent bonds, which are composed of sulfhydryl cysteine residues and stores the metal by tightly chelating the metal. Typically, it is assumed that MTs have two binding domains, one of which is the C-terminal part (α-domain) with three binding sites. The other one is the N-terminal part (β-domain) with four divalent binding sites . Therefore, MTs are important for protecting the cell against heavy metal toxicity and maintaining cellular homeostasis.

Cobalt Metallothionein

part:BBa K3275001 is originally from Rainbow trout metallothionein, which is called MTA (Metallothionein A) that has similar structures with Metallothionein-1A (part:BBa_K3275000). Both MTs have α and β domains that contain 11 and 9 cysteines. Figure 1 shows the structure of MTA .

For part:BBa_K3275001, some bases from the original sequence are changed due to synthesis demands.
