C‐terminal Cysteines of CueR Act as Auxiliary Metal

2019-7-31  This implies a mechanism where the specificity of CueR for monovalent coinage metal ions and against divalent metal ions is achieved by coordination to divalent metal ions by the CCHH motif, preventing the docking of the C‐terminal helix into the hydrophobic pocket, 5 and consequently inhibiting activation of transcription.

Nature of Alkali‐ and Coinage‐Metal Bonds versus

We find that coinage-metal bonds are stronger than alkali-metal bonds which are stronger than the corresponding hydrogen bonds. Our main purpose is to understand how and why the structure, stability and nature of such bonds are affected if the monovalent central atom H of hydrogen bonds is replaced by an isoelectronic alkali- or coinage-metal atom.
