Breakthrough in metal-free enzyme design for green catalysis

Caption

Researchers at Institute of Science Tokyo have developed a highly active artificial peroxidase enzyme using histidine clusters within a ferritin protein cage—without requiring metal ions. This innovation mimics natural enzymes and achieves over 80 times greater catalytic efficiency than traditional oligohistidine assemblies, opening new avenues for sustainable chemical production, biomaterials, and environmental remediation.
