    • Biochemical and structural characterisation of a family GH5 cellulase from endosymbiont of shipworm P. megotara 

      Junghare, Madan; Manavalan, Tamilvendan; Fredriksen, Lasse; Leiros, Ingar; Altermark, Bjørn; Eijsink, Vincent; Vaaje-Kolstad, Gustav (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-04)
      Background Cellulases play a key role in the enzymatic conversion of plant cell-wall polysaccharides into simple and economically relevant sugars. Thus, the discovery of novel cellulases from exotic biological niches is of great interest as they may present properties that are valuable in the biorefning of lignocellulosic biomass. Results We have characterized a glycoside hydrolase 5 (GH5) domain ...

    • Discovery and characterization of a thermostable two-domain GH6 endoglucanase from a compost metagenome 

      Jensen, Marianne Slang; Fredriksen, Lasse; Mackenzie, Alasdair; Pope, Phillip; Leiros, Ingar; Chylenski, Piotr; Williamson, Adele Kim; Christopeit, Tony; Østby, Heidi; Vaaje-Kolstad, Gustav; Eijsink, Vincent (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-24)
      Enzymatic depolymerization of recalcitrant polysaccharides plays a key role in accessing the renewable energy stored within lignocellulosic biomass, and natural biodiversities may be explored to discover microbial enzymes that have evolved to conquer this task in various environments. Here, a metagenome from a thermophilic microbial community was mined to yield a novel, thermostable cellulase, named ...

    • Structure and function of a CE4 deacetylase isolated from a marine environment 

      Tuveng, Tina Rise; Rothweiler, Ulli; Udatha, D.B.R.K. Gupta; Vaaje-Kolstad, Gustav; Smalås, Arne O.; Eijsink, Vincent (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-06)
      Chitin, a polymer of β(1–4)-linked N-acetylglucosamine found in e.g. arthropods, is a valuable resource that may be used to produce chitosan and chitooligosaccharides, two compounds with considerable industrial and biomedical potential. Deacetylating enzymes may be used to tailor the properties of chitin and its derived products. Here, we describe a novel CE4 enzyme originating from a marine ...
