The Paleozoic Origin of Enzymatic Lignin Decomposition Reconstructed from 31 Fungal Genomes
Comparative analyses of 31 fungal genomes suggest that lignin-degrading peroxidases expanded in the lineage leading to the ancestor of the Agaricomycetes, which is reconstructed as a white rot species, and then contracted in parallel lineages leading to brown rot and mycorrhizal species.

Broadening the knowledge of lignocellulose biodegradation processes should contribute to better control of wood-decaying fungi, as well as to the development of new biocatalysts of industrial interest based on these organisms and their enzymes.

Phenolic aldehydes, ketones, acids, and esters related to the three lignin units were among the best mediators, including p-coumaric acid, vanillin, acetovanillone, methyl vanillate, and above all, syringaldehyde and acetosyringone, which are especially promising as ecofriendly (and potentially cheap) mediators for industrial applications.

Comparisons with the closely relatedwhite-rot fungus Phanerochaete chrysosporium support an evolutionary shift from white-rot to brown-rot during which the capacity for efficient depolymerization of lignin was lost.

Two major peroxidases are secreted by the fungus Pleurotus eryngii in lignocellulose cultures, and a three-dimensional model suggests high structural affinity of this versatilePeroxidase PS1 with LiP but shows a putative Mn2+ binding site near the internal heme propionate.
