Sculpting Metal‐binding Environments in De Novo Designed Three‐helix Bundles [PDF]
, 2015 De novo protein design is a biologically relevant approach used to study the active centers of native metalloproteins. In this review, we will first discuss the design process in achieving α3D, a de novo designed three‐helix bundle peptide with a well ...

ChemPhysChem, Volume 27, Issue 2, January 2026.We performed electron paramagnetic resonance (EPR) experiments to reveal that P. aerguinosa CueR copper transcription factor enhances expression of copZ2 more strongly than mexPQ‐opmE under copper stress, consistent with their detoxification roles. Findings highlight EPR as a key tool for probing metal‐regulated transcription.
