Journal ArticleDOI
An oxidative enzyme boosting the enzymatic conversion of recalcitrant polysaccharides.
Gustav Vaaje-Kolstad,Bjørge Westereng,Svein Jarle Horn,Zhanliang Liu,Hong Zhai,Morten Sørlie,Vincent G. H. Eijsink +6 more
TL;DR: An enzyme is described that acts on the surface of crystalline chitin, where it introduces chain breaks and generates oxidized chain ends, thus promoting further degradation by chit inases, demonstrating the existence of a hitherto unknown enzyme activity.
Journal ArticleDOI
Novel enzymes for the degradation of cellulose
TL;DR: This work describes recent developments in enzyme technology for conversion of cellulose, the most abundant, homogeneous and recalcitrant polysaccharide in lignocellulosic biomass, and focuses on a recently discovered new type of enzymes currently classified as CBM33 and GH61 that catalyze oxidative cleavage ofpolysaccharides.
Journal ArticleDOI
Discovery of LPMO activity on hemicelluloses shows the importance of oxidative processes in plant cell wall degradation
Jane Wittrup Agger,Trine Isaksen,Anikó Várnai,Silvia Vidal-Melgosa,William G.T. Willats,Roland Ludwig,Svein Jarle Horn,Vincent G. H. Eijsink,Bjørge Westereng,Bjørge Westereng +9 more
TL;DR: It is demonstrated for the first time that an LPMO from Neurospora crassa, NcLPMO9C, indeed degrades various hemicelluloses, in particular xyloglucan, and this finding dramatically widens the scope of LPMOs and oxidative processes in plant cell wall degradation and biorefining.
Journal ArticleDOI
Cleavage of cellulose by a CBM33 protein.
Zarah Forsberg,Gustav Vaaje-Kolstad,Bjørge Westereng,Anne C. Bunæs,Yngve Stenstrøm,Alasdair Mackenzie,Morten Sørlie,Svein Jarle Horn,Vincent G. H. Eijsink +8 more
TL;DR: It is shown that some members of the CBM33 family cleave crystalline cellulose as demonstrated by chromatographic and mass spectrometric analyses of soluble products released from Avicel or filter paper on incubation with CelS2, a CBM 33‐containing protein from Streptomyces coelicolor A3(2).
Journal ArticleDOI
A C4-oxidizing Lytic Polysaccharide Monooxygenase Cleaving Both Cellulose and Cello-oligosaccharides
Trine Isaksen,Bjørge Westereng,Bjørge Westereng,Finn Lillelund Aachmann,Jane Wittrup Agger,Daniel Kracher,Roman Kittl,Roland Ludwig,Dietmar Haltrich,Vincent G. H. Eijsink,Svein Jarle Horn +10 more
TL;DR: This study provides unequivocal evidence for C4 oxidation of the nonreducing end sugar and demonstrates a novel LPMO substrate specificity.
