    • 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 ...

    • Metagenomics of the Svalbard Reindeer Rumen Microbiome Reveals Abundance of Polysaccharide Utilization Loci 

      Pope, Phillip B; Mackenzie, Alasdair; Gregor, Ivan; Smith, Wendy; Sundset, Monica Alterskjær; McHardy, Alice; Morrison, Mark; Eijsink, Vincent (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Lignocellulosic biomass remains a largely untapped source of renewable energy predominantly due to its recalcitrance and an incomplete understanding of how this is overcome in nature. We present here a compositional and comparative analysis of metagenomic data pertaining to a natural biomass-converting ecosystem adapted to austere arctic nutritional conditions, namely the rumen microbiome of Svalbard ...

    • Structural insights of the enzymes from the chitin utilization locus of Flavobacterium johnsoniae 

      Mazurkewich, Scott; Helland, Ronny; Mackenzie, Alasdair; Eijsink, Vincent; Pope, Phillip Byron; Brändén, Gisela; Larsbrink, Johan (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-13)
      Chitin is one of the most abundant renewable organic materials found on earth. The chitin utilization locus in <i>Flavobacterium johnsoniae</i>, which encodes necessary proteins for complete enzymatic depolymerization of crystalline chitin, has recently been characterized but no detailed structural information on the enzymes was provided. Here we present protein structures of the <i>F. johnsoniae</i> ...
