Introduction

Once heavy metals have entered the cell it is key to keep them there. As these metals are toxic to cell survival in critical amounts evolution has provided us with biological detoxicification proteins such as [http://en.wikipedia.org/wiki/Metallothionein metallothioneins]. These proteins can aid us in our quest to accumulate a variaty of heavy metals as they bind to a wide range of metals including cadmium, zinc, mercury, copper, arsenic, silver, etc..

Metallothioneins

Metallothioneins are a class of low molecular-weight metal-binding proteins rich in cysteines residues. They are capable of binding a variety of heavy metals. And they have readily been used to create cell based systems for purification of contaminated water [http://www.ncbi.nlm.nih.gov/pubmed/9758654][http://www.ncbi.nlm.nih.gov/pubmed/18618649]. In addition to their wide application possibilities they also have the capacity to carry multiple metal ions at one time, in contrast to some other metalloproteins that carry them one-on-one[http://www.ncbi.nlm.nih.gov/pubmed/9579658]. Many forms of metallothioneins are known and their affinity for different metals has been investigated on several occasions, such as for cadmium[http://www.ncbi.nlm.nih.gov/pubmed/16890348], arsenic [http://www.ncbi.nlm.nih.gov/pubmed/16984198][http://www.ncbi.nlm.nih.gov/pubmed/15294789][http://www.ncbi.nlm.nih.gov/pubmed/18326684], mercuryhttp://www.ncbi.nlm.nih.gov/pubmed/9758654 1[http://www.ncbi.nlm.nih.gov/pubmed/9342882][http://www.ncbi.nlm.nih.gov/pubmed/17920767], nickel[http://www.ncbi.nlm.nih.gov/pubmed/12727263] or a combination of metalshttp://www.ncbi.nlm.nih.gov/pubmed/9579658 3[http://www.ncbi.nlm.nih.gov/pubmed/18313216]. Metal-protein complexes can be quantified using a fluorescent molecule[http://www.ncbi.nlm.nih.gov/pubmed/19133293].
