Peptide-Gold Nanoparticle Conjugates as Artificial Carbonic Anhydrase Mimics [PDF]
We herein describe the design and synthesis of a catalytically active peptide–gold nanoparticle conjugate (Pep-Au-NP) that binds Zn(II) within its peptide monolayer and develops carbonic anhydrase activity. Specifically, a modified variant of the β-sheet
