Design Notes

Similar method as MBP(mercury) is constructed was applied to PbrR. Firstly,Sequence alignment of MerR and PbrR has been carried out. Previous work showed that MerR family TFs share a highly conserved homology at their metal binding domains (Brown et al., 2003; Hobman, 2007), which implies that our strategies of bioabsorbent engineering might be applicable to other cases of heavy metals. We again design a single polypeptide consisting of two dimerization helixes and metal binding loops of PbrR, to form an antiparallel coiled coil MBP mimicking the dimerized metal binding domains of the wild-type as Figure(B) shows.Figure (C) shows that the MBP was constructed by fusing two copies of metal binding domain of PbrR in tandem via the same method with mercury MBP.
