AG3
AG3 is an inorganic-binding polypeptide that specifically recognizes Ag/Au surfaces. In silver systems, AG3 induces the reduction of Ag+ and regulates microcrystal morphology. In gold systems, AG3 acts as a non-reducing, high-affinity inhibitor that modulates nucleation-growth kinetics through interactions with metal clusters/surfaces to achieve size/morphology control. AG3 can be immobilized on polymer films, phages or nanosubstrates for applications in biomimetic mineralization, biosensors, precious metal recovery and patterned graphite templates.

Description
In Vitro
AG3 promotes the reduction of Ag+ to Ag0[1] during in vitro biomimetic synthesis.
AG3 can induce the formation of hexagonal, triangular and cubic silver microcrystal morphologies in vitro; its secondary structure in solution undergoes only minor changes after binding to silver[1].
AG3 inhibits the nucleation and surface reaction-limited growth processes of Au nanocrystals formed from Au (III) ions[2].
AG3 cannot reduce gold ions independently; it modulates the HEPES-mediated AuIII reduction mechanism, thereby preventing the formation of irregular precipitates[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
