SmtA metallothionein protein as a fusion partner

SmtA metallothionein protein from E. coli can bind to heavy metals [1,2,3]. They have a tendency to bind to cationic metal ions such as cadmium, copper, arsenic, mercury, silver.

This part can be used as a fusion partner to other proteins. E.g. when fused to Gfp, it can be seen by the microscope.
