Design Notes

We got smt O-P and smtA, a fragment coding MT-like to sequester metal ions from smt locus by PCR and overlaped two fragments,smtB-smt O-P and pigment gene.Binding with smtB, smt O-P represses the expression of reporter genes.In the presence of heavy metal,the pigment and SmtA can expression normally.

smt O-P is a part of smt locus from Synechococcus elongates PCC7942.
