Nickel(II) dependent promotor with luxAB as reporter
The biobrick contains the RcnA promotor from E. coli fused with the luxAB reporter gene. E. coli strains own the RcnR-regulator gene which directly regulates the transcription of the RcnA nickel-cobalt efflux protein from which the promotor is amplified. In absence of Ni(II), RcnR represses the rcnA-promoter. After addition of Ni (II) (NiCl2), RcnR binds this ion and is released from the promoter. Therefore, luxAB will be expressed.
--> also use luxCDE or luciferine to detect output.
In presence of nickel the Luciferase is expressed.
The promoter is also a little bit sensitive for Co 2+.
Usage and Biology
