Many prokaryotes are diderms. They divide using an FtsZ division ring to simultaneously constrict physically coupled inner and outer membranes to form daughter cells with two membranes. Currently, only one archaeon, Ignicoccus hospitalis, is known to have an outer and inner membrane. Here, in exploring Ignicoccus cell...

Surface layers (S-layers) are paracrystalline protein lattices that form the outermost boundary of many archaeal and bacterial cells. Interest in S-layer biology has grown rapidly in recent years, driven by advances in structural and bioinformatic studies that have revealed new insights into lattice organization and fu...

Surface layers (S-layers) are paracrystalline protein lattices that form the outermost layer of the cell envelope in most archaea, providing structural support, protecting against external insults, and co-ordinating interactions with their environment. Despite their widespread occurrence, the molecular and structural d...

An electron cryomicroscopy structure of the 60 kDa CdrA adhesive N-terminus is reported, which combined with electron cryotomography of focused-ion beam milled specimens, allows for a complete in situ model of the native adhesin and reveals a small adhesive domain (called ADEPT) at the distal tip of CdrA that is nearly...

The possibility that microtubule architecture and dynamics evolved in Asgard archaea prior to eukaryogenesis is raised, as well as the broad occurrence of tubulins in Asgard archaea.
