AI Article Synopsis
- CupR is a metalloregulatory protein from Ralstonia metallidurans that specifically responds to gold stress.
- It utilizes a unique distorted trigonal geometry to effectively bind to gold ions.
- The protein shows an extremely high sensitivity for gold(I) with a dissociation constant (K(d)) of approximately 10(-35) M.
Article Abstract
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) approximately 10(-35) M) and selective recognition of gold(I).
