    Agl24 is an ancient archaeal homolog of the eukaryotic N-glycan chitobiose synthesis enzymes

    Benjamin H Meyer, Panagiotis S Adam ... Helge C Dorfmueller
    The crenarchaeon Sulfolobus synthesizes the N-glycan core in the identical way as all Eukaryotes, which strengthens the hypothesis that the eukaryotic N-glycosylation is acquired from an ancient archaeon during eukaryogenesis.

    Structure and in situ organisation of the Pyrococcus furiosus archaellum machinery

    Bertram Daum, Janet Vonck ... Werner Kühlbrandt
    Using both electron cryo-tomography and helical reconstruction, the first structure of the entire archaellum machinery with an assembled filament has been determined, providing the structural basis for our understanding of archaeal motility.

    Pyruvate:ferredoxin oxidoreductase and low abundant ferredoxins support aerobic photomixotrophic growth in cyanobacteria

    Yingying Wang, Xi Chen ... Kirstin Gutekunst
    Synechocystis switches its redox pools under reducing photomixotrophic conditions from utilizing NAD(H)- to ferredoxin-dependent enzymes and thereby balances its metabolism in a trade-off between energy conservation and chemical driving forces.

    Amidst multiple binding orientations on fork DNA, Saccharolobus MCM helicase proceeds N-first for unwinding

    Himasha M Perera, Michael A Trakselis
    The archaeal MCM helicase can load in multiple orientations on DNA but translocation proceeds with a leading N-terminal domain, which affects double hexamer activation at origins of replication.

    Global analysis of cytosine and adenine DNA modifications across the tree of life

    Sreejith Jayasree Varma, Enrica Calvani ... Markus Ralser
    By using mass spectrometry, we determined the global levels of various DNA modifications across species and tissues.
