Actions biochimiques/physiologiques

La laccase catalyse l′oxydation de composés phénoliques, notamment la lignine, via la réduction d′oxygène en eau. La présence de médiateurs permettra aussi l′oxydation de composés non phénoliques. La fonction principale de la laccase est la dégradation de la lignine par les champignons.

Définition de l'unité

One unit corresponds to the amount of enzyme which converts 1 μmole of catechol per minute at pH 4.5 and 25 °C

Laccases, as early as 1959, were proposed to catalyze the oxidative polymerization of monolignols. Genetic evidence in support of this hypothesis has been elusive due to functional redundancy of laccase genes. An Arabidopsis double mutant demonstrated the involvement of laccases

Numerous efforts have been made to remove emerging trace organic contaminants, such as pharmaceuticals and personal care products (PPCPs). This study examined the removal of N,N-diethyl-m-toluamide (DEET) by Trametes versicolor laccase and its laccase-mediator systems. Experimental results showed that DEET
