Unnatural amino acid substitution as a probe of the allosteric coupling pathway in a mycobacterial Cu(I) sensor

[Image: see text] The Cu(I) sensor Mycobacterium tuberculosis CsoR is a founding member of a new metalloregulatory protein family. Here we show that two "atom" substitutions of the Nε2 face of a Cu(I) coordinating histisine-61 allosterically uncouple Cu(I) and DNA binding, with no effect o...
