The impact of the carbohydrate-binding module on how a lytic polysaccharide monooxygenase modifies cellulose fibers

Biotechnology for Biofuels and Bioproducts
Background In recent years, lytic polysaccharide monooxygenases (LPMOs) that oxidatively cleave cellulose have gained increasing attention in cellulose fiber modification.

Action of lytic polysaccharide monooxygenase on plant tissue is governed by cellular type

Scientific Reports, 2017
Lignocellulosic biomass bioconversion is hampered by the structural and chemical complexity of the network created by cellulose, hemicellulose and lignin.

Trichoderma reesei tselluloosaktiivse lüütilise polüsahhariidi monooksügenaasi TrAA9A toimemehhanismi kineetiline iseloomustamine [PDF]

, 2020
Hiljuti avastatud polüsahhariide lagundavad lüütilised polüsahhariidi monooksügenaasid (LPMO-d) on redoksensüümid, mis katalüüsivad polüsahhariidses substraadis oksüdatiivseid lõikeid ning on võimelised lagundama kristallilist tselluloosi.

Electrochemical Monitoring of Heterogeneous Peroxygenase Reactions Unravels LPMO Kinetics

ACS Catalysis
Biological conversion of plant biomass depends on peroxygenases and peroxidases acting on insoluble polysaccharides and lignin. Among these are cellulose- and hemicellulose-degrading lytic polysaccharide monooxygenases (LPMOs), which have revolutionized our concept of biomass degradation.

Assesing the enzymatic effects of cellulases and LPMO in improving mechanical fibrillation of cotton linters

Background The increasing interest in replacing petroleum-based products by more sustainable materials in the packaging sector gives relevance to cellulose as a biodegradable natural resource.

Enzyme mediated nanofibrillation of cellulose by the synergistic actions of an endoglucanase, lytic polysaccharide monooxygenase (LPMO) and xylanase

, 2018
Physiochemical methods have generally been used to “open-up” biomass substrates/pulps and have been the main method used to fibrillate cellulose. However, recent work has shown that canonical cellulase enzymes such as endoglucanases, in combination with “

On the formation and role of reactive oxygen species in light-driven LPMO oxidation of phosphoric acid swollen cellulose.

, 2017
Light-driven activation of lytic polysaccharide monooxygenases (LPMOs) has been attributed to the transfer of high redox potential electrons from excited photopigments to the enzyme.
