Ni(II) dependent rcnA-promoter and GFP

E. coli has an RcnR-regulator that switches on the RcnA-Promotor in the presence of Ni(II). After induction GFP will be expressed.

E. coli has to be used as reporter organism since RcnR is not coded on the plasmid.

Usage and Biology

This BioBrick can be used to detect Ni(II)-Ions in water.

This is how it works:

The sensor is also sensing Co 2+, but not very sensitivly.
