  • PubMed Abstract: 

    The promotion of protein dimerization using the aggregation properties of a protein ligand was explored and shown to produce complexes with unusual stoichiometries. Helical foldamer 2 was synthesized and bound to human carbonic anhydrase (HCA) using a nanomolar active site ligand. Crystal structures show that the hydrophobicity of 2 and interactions of its side chains lead to the formation of an HCA 2 -2 3 complex in which three helices of 2 are stacked, two of them being linked to an HCA molecule. The middle foldamer in the stack can be replaced by alternate sequences 3 or 5. Solution studies by CD and NMR confirm left-handedness of the helical foldamers as well as HCA dimerization.
