Method & Evidence

AimTo investigate the efficacy of Agaricus arvensis-derived silver nanoparticles (AgNPs) as a platform for immobilizing tyrosine hydroxylase (TH) to enhance the biotransformation of L-tyrosine to L-DOPA.

MethodExperimental research and material characterization

ProcedureSilver nanoparticles were synthesized using Agaricus arvensis mushroom extract. The extract acted as a reducing and stabilizing agent. The synthesized AgNPs were characterized using UV–Vis spectroscopy, SEM, FTIR, and XRD. Particle size was further analyzed by SEM and Zeta-sizer. The enzyme tyrosine hydroxylase (TH) was immobilized onto these AgNPs. The immobilized enzyme was then used for the aerobic biotransformation of synthetic L-tyrosine to L-DOPA, and its performance was compared to the free enzyme.
