Applications of BBa_K190019

fMT can be used to sequester metal ions like arsenite (As-III) or arsenate (As-V), this can be used to give the bacterium a higher resistance against arsenic. But the protein can also be used as a delay system together with a metal sensitive promoter (as BBa_K190023), as it sequesters the arsenic as soon as it enters the cell. Upon overexpression of the protein it would take some time before it is saturated and free arsenic can reach the promoter regulator protein (like ArsR). Alternatively the protein can be used to use bacteria for biomining of arsenic, as the presence of rare metals will also become less prominent, like the fossil oil problem the earth just has a maximum amount of some compounds.
