Tryptophan Cu(I)–π interaction fine-tunes the metal binding properties of the bacterial metallochaperone CusF

The periplasmic metallochaperone CusF coordinates Cu(I) and Ag(I) through a unique site consisting of a Met(2)His motif as well as a Cu(I)–π interaction between a nearby tryptophan, W44, and the metal ion. Through mutational analyses we investigate here the role that W44 in CusF plays in metal coord...
