Lignin-modifying enzymes (LMEs) are various types of enzymes produced by fungi and bacteria that catalyze the breakdown of lignin, a biopolymer commonly found in the cell walls of plants. The terms ligninases and lignases are older names for the same class, but the name "lignin-modifying enzymes" is now preferred, given that these enzymes are not hydrolytic but rather oxidative (electron withdrawing) by their enzymatic mechanisms. LMEs include peroxidases, such as lignin peroxidase (EC 1.11.1.14), manganese peroxidase (EC 1.11.1.13), versatile peroxidase (EC 1.11.1.16), and many phenoloxidases of the laccase type.

  • Lignin-modifying enzymes (LMEs) are various types of enzymes produced by fungi and bacteria that catalyze the breakdown of lignin, a biopolymer commonly found in the cell walls of plants. The terms ligninases and lignases are older names for the same class, but the name "lignin-modifying enzymes" is now preferred, given that these enzymes are not hydrolytic but rather oxidative (electron withdrawing) by their enzymatic mechanisms. LMEs include peroxidases, such as lignin peroxidase (EC 1.11.1.14), manganese peroxidase (EC 1.11.1.13), versatile peroxidase (EC 1.11.1.16), and many phenoloxidases of the laccase type. LMEs have been known to be produced by many species of white rot basidiomycetous fungi, including: Phanerochaete chrysosporium, , Trametes versicolor, Phlebia radiata, Pleurotus ostreatus and Pleurotus eryngii. LMEs are produced not only by wood-white rotting fungi but also by litter-decomposing basidiomycetous fungi such as Agaricus bisporus (common button mushroom), and many Coprinus and Agrocybe species. The brown-rot fungi, which are able to colonize wood by degrading cellulose, are only able to partially degrade lignin. Some bacteria also produce LMEs, although fungal LMEs are more efficient in lignin degradation. Fungi are thought to be the most substantial contributors to lignin degradation in natural systems. LMEs and cellulases are crucial to ecologic cycles (for example, growth/death/decay/regrowth, the carbon cycle, and soil health) because they allow plant tissue to be decomposed quickly, releasing the matter therein for reuse by new generations of life. LMEs are also crucial to a number of different industries. (en)
  • Une ligninase est une oxydoréductase fongique extracellulaire qui catalyse la dégradation de la lignine par oxydation. La lignine est un polymère constituant une fraction importante de la paroi cellulaire des plantes. Ces enzymes, parmi lesquelles on compte la lignine peroxydase, la manganèse peroxydase, la (en) et des enzymes oxydant les phénols de type laccase, devraient plus justement être appelées enzymes de modification de la lignine, car ce ne sont pas des hydrolases. Ces enzymes sont produites par plusieurs espèces de champignons telles que (en), , Trametes versicolor, Phlebia radiata, Pleurotus ostreatus et Pleurotus eryngii. On les trouve également chez les Basidiomycota tels que Agaricus bisporus et de nombreuses espèces de Coprinus et d’Agrocybe. Des enzymes apparentées ont également été observées chez des espèces de bactéries filamenteuses telles que T7A, REN-7 et (en) ; cependant, la dégradation efficace de la lignine n'a pu être réalisée qu'avec des peroxydases fongiques et des laccases combinées à des composés à transfert de charge. * Portail de la chimie (fr)
  • Ligninaser är en typ av ligninnedbrytande enzymer. Ligninaser syntetiseras av en rad olika organismer, bland andra vitrötesvampar, mjukrötesvampar, brunrötesvampar och vissa humuslevande svampar. Generellt är ligninaser , och ofta samarbetar de med en lågmolekylär kofaktor. Exempel på ligninaser är ligninperoxidas, manganperoxidas, lackas och cellobiosdehydrogenas. (sv)
