Abstract
Description
technical field
[0001] The invention belongs to the technical field of genetic engineering, and specifically relates to a metallothionein gene, a metallothionein encoded by the gene, expression and application thereof. Background technique
[0002] Metallothionein (MT for short) is a class of metal-binding proteins ubiquitous in living organisms. Metallothionein is a low molecular weight protein with metal binding capacity and high inducibility properties. A cysteine-rich short peptide with a high affinity for various heavy metals. It is a low molecular weight protein with a very high content of cysteine residues and metals. The metals combined with it are mainly cadmium, copper and zinc, which widely exist in various organisms from microorganisms to humans, and their structures are highly conserved.
[0003] Heavy metal bioremediation is a technology that uses biological materials for heavy metal treatment, and heavy metal resistance genes are important resources for b...
