In eukaryotic cells, the ubiquitylation system regulates several cellular processes central to protein homoeostasis. Here the authors demonstrate the existence of an eukaryotic-like ubiquitylation cascade requiring E1, E2 and E3-like enzymes in the a

Asgard archaea have recently been identified as the closest archaeal relatives of eukaryotes. Their ecology, and particularly their virome, remain enigmatic. We reassembled and closed the chromosome of Candidatus Odinarchaeum yellowstonii LCB_4, thro

Calditrichaeota is a recently recognized bacterial phylum with three cultured representatives, isolated from hydrothermal vents. Here we expand the phylogeny and ecology of this novel phylum with metagenome-derived and single-cell genomes from six un

The origin of eukaryotes represents an unresolved puzzle in evolutionary biology. Current research suggests that eukaryotes evolved from a merger between a host of archaeal descent and an alphaproteobacterial endosymbiont. The discovery of the Asgard
