Abstract

Guanosine 5'-monophosphate (5'-GMP) and Fe(iii)-heme form a supramolecular catalyst with peroxidase activity. Catalysis, which depends on self-assembly of 5'-GMP into a G-quadruplex that binds hemin, can be modulated by nucleotide concentration, temperature and the identity of the nucleotide's sugar.
