Mechanism, kinetic model and structural elements involved in laccase functional properties and reaction. a Representation of the laccase mechanism of action in the active site of Trametes versicolor laccase (PDB 1KYA). In orange are represented those aminoacids involved in the binding, stabilization and orientation of the substrate, in grey and green those that are involved in the coordination of catalytic coppers and the electron transfer and in yellow those that transfer protons for the oxygen assisted reduction. b Laccase action on a lignin-model illustrating the domino effect [198]. c Complex two-site ping-pong bi-bi kinetic model proposed for the laccase reaction [184, 185]. d Structural and functional elements involved in different steps of the laccase reaction
