Journal ArticleDOI
Lytic polysaccharide monooxygenases disrupt the cellulose fibers structure
Ana Villares,Céline Moreau,Chloé Bennati-Granier,Sona Garajova,Loïc Foucat,Xavier Falourd,Bodo Saake,Jean-Guy Berrin,Bernard Cathala +8 more
TL;DR: This work provides the first evidence of the direct oxidative action of LPMOs with the mechanical weakening of the cellulose ultrastructure.
Journal ArticleDOI
Substrate specificity and regioselectivity of fungal AA9 lytic polysaccharide monooxygenases secreted by Podospora anserina
Chloé Bennati-Granier,Chloé Bennati-Granier,Sona Garajova,Sona Garajova,Sona Garajova,Charlotte Champion,Charlotte Champion,Sacha Grisel,Sacha Grisel,Mireille Haon,Mireille Haon,Simeng Zhou,Simeng Zhou,Mathieu Fanuel,David Ropartz,Hélène Rogniaux,Isabelle Gimbert,Isabelle Gimbert,Eric Record,Eric Record,Jean-Guy Berrin,Jean-Guy Berrin +21 more
TL;DR: This study provides insights into the mode of cleavage and substrate specificities of fungal AA9 LPMOs that will facilitate their application for the development of future biorefineries.
Journal ArticleDOI
Single-domain flavoenzymes trigger lytic polysaccharide monooxygenases for oxidative degradation of cellulose.
Sona Garajova,Yann Mathieu,Maria Rosa Beccia,Chloé Bennati-Granier,Frédéric Biaso,Mathieu Fanuel,David Ropartz,Bruno Guigliarelli,Eric Record,Hélène Rogniaux,Bernard Henrissat,Jean-Guy Berrin +11 more
TL;DR: This work investigates the ability of AA3_2 flavoenzymes secreted under lignocellulolytic conditions to trigger oxidative cellulose degradation by AA9 LPMOs and shows that glucose dehydrogenase and aryl-alcohol quinone oxidoreductases are catalytically efficient electron donors for L PMOs.
Journal ArticleDOI
The Podospora anserina lytic polysaccharide monooxygenase PaLPMO9H catalyzes oxidative cleavage of diverse plant cell wall matrix glycans.
Mathieu Fanuel,Sona Garajova,David Ropartz,Nicholas McGregor,Harry Brumer,Hélène Rogniaux,Jean-Guy Berrin +6 more
TL;DR: The ability of PaLPMO9H to target polysaccharides, differing from cellulose by their linkages, glycosidic composition and/or presence of sidechains, could be advantageous for this coprophilous fungus when catabolizing highly variable polysacCharides and for the development of optimized enzyme cocktails in biorefineries.
Journal ArticleDOI
Salt-responsive lytic polysaccharide monooxygenases from the mangrove fungus Pestalotiopsis sp. NCi6
Ilabahen Patel,Daniel Kracher,Su Ma,Sona Garajova,Mireille Haon,Craig B. Faulds,Jean-Guy Berrin,Roland Ludwig,Eric Record +8 more
TL;DR: Two new LPMOs from the mangrove fungus Pestalotiopsis sp.
