Construction of a Soluble Supramolecular Glutathione Peroxidase Mimic based on Host-Guest Interaction
A soluble glutathione peroxidase mimic with the optimum structure (NCD-Te-NCD2.2) was constructed
based on the supramolecular host-guest interaction. The self-assembled structure and catalytic
mechanism of NCD-Te-NCD2.2 were detailed investigation. It was proved that NCD-Te-NCD2.2 could form
the hollow vesicle-like aggregates in water. And saturation kinetics measurement indicated that NCD-Te-
NCD2.2 exhibited the typical enzyme catalytic behavior. Furthermore, benefited from the hydrophobic microenvironment
in vesicle-like aggregates, NCD-Te-NCD2.2 exhibited the specific recognition ability for hydrophobic
substrates, which was one of the important characteristics of native glutathione peroxidase. The successful construction
of NCD-Te-NCD2.2 not only provides an efficient preparation method for soluble GPx mimic but also highlights
for construction of other giant supramolecular biomimetic enzymes.
