Laccase-like activity
WebAug 5, 2024 · Laccase immobilization means coupling the enzyme to an insoluble carrier matrix, which are traditionally classified into entrapment/encapsulation, covalent bonding, cross-linking and adsorption methods. Among the existing laccase immobilization methods, adsorption is the simplest and common method. WebIn this work, we report an exceptionally simple yet functional laccase mimic based on guanosine monophosphate (GMP) coordinated copper. It forms an amorphous metal–organic framework (MOF) material. The ratio of copper and GMP is 3:4 as determined by isothermal titration calorimetry.
