Energy flux controls tetraether lipid cyclization in Sulfolobus acidocaldarius
Microorganisms regulate the composition of their membranes in response to environmental cues. Many archaea maintain the fluidity and permeability of their membranes by adjusting the number of cyclic moieties within the cores of their glycerol ...

Replication-biased genome organisation in the crenarchaeon
Background Species of the crenarchaeon Sulfolobus harbour three replication origins in their single circular chromosome that are synchronously initiated during replication.

Electron cryo-microscopy reveals the structure of the archaeal thread filament
Pili are filamentous appendages on the surface of bacteria and archaea, and play roles in multiple processes such as adhesion, motility and horizontal gene transfer. Here, Gaines et al. describe the structure of a new type of pilus, termed ‘thread’, from

Only a few archaeal filamentous viruses have been structurally characterized. Here the authors describe the membrane-enveloped Sulfolobus filamentous virus 1 that infects Sulfolobus shibatae and present its 3.7 Å resolution cryo-EM structure, which ...

Biological Membranes in Extreme Conditions: Simulations of Anionic Archaeal Tetraether Lipid Membranes. [PDF]
In contrast to the majority of organisms that have cells bound by di-ester phospholipids, archaeal membranes consist of di- and tetraether phospholipids.

Surface resistance to SSVs and SIRVs in pilin deletions of Sulfolobus islandicus
Characterizing the molecular interactions of viruses in natural microbial populations offers insights into virus–host dynamics in complex ecosystems. We identify the resistance of Sulfolobus islandicus to Sulfolobus spindle‐shaped virus (SSV9) conferred ...

Endogenous Mutagenesis in Recombinant Sulfolobus Plasmids [PDF]
ABSTRACT Low rates of replication errors in chromosomal genes of Sulfolobus spp. demonstrate that these extreme thermoacidophiles can maintain genome integrity in environments with high temperature and low pH. In contrast to this genetic stability, we observed unusually frequent mutation of the β-

Architecture and modular assembly of Sulfolobus S-layers revealed by electron cryotomography
Significance Many bacteria and most archaea are enveloped in S-layers, protective lattices of proteins that are among the most abundant on earth. S-layers define both the cell’s shape and periplasmic space, and play essential roles in cell division ...

Prediction of mutations on structure primase of the archaeon Sulfolobus solfataricus
All living organisms need a DNA replication mechanism and it has been conserved in the three domains of life throughout evolutionary process. Primase is the enzyme responsible for synthesizing de novo RNA primers in DNA replication. Archaeo-Eukaryotic
