Highly Sensitive and Selective Gold(I) Recognition by a Metalloregulator in Ralstonia metallidurans
A MerR family metalloregulatory protein CupR selectively responds to gold stress in Ralstonia metallidurans. A distorted trigonal geometry appears to be used by CupR to achieve the highly sensitive (K-d similar to 10(-35) M) and selective recognition of gold (I).
