Anti-CRISPR-Based and CRISPR-Based Genome Editing of Sulfolobus islandicus Rod-Shaped Virus 2

open access: yesViruses, 2018
Genetic engineering of viruses has generally been challenging. This is also true for archaeal rod-shaped viruses, which carry linear double-stranded DNA genomes with hairpin ends.

Differentiation and Structure in Sulfolobus islandicus Rod-Shaped Virus Populations

open access: yesViruses, 2017
In the past decade, molecular surveys of viral diversity have revealed that viruses are the most diverse and abundant biological entities on Earth. In culture, however, most viral isolates that infect microbes are represented by a few variants isolated ...

Archaeal GPN-loop GTPases involve a lock-switch-rock mechanism for GTP hydrolysis

open access: yesmBio, 2023
Three GPN-loop GTPases, GPN1–GPN3, are central to the maturation and trafficking of eukaryotic RNA polymerase II. This GTPase family is widely represented in archaea but typically occurs as single paralogs.

Chromosome organization affects genome evolution in Sulfolobus archaea

open access: yesNature Microbiology, 2022
In all organisms, the DNA sequence and the structural organization of chromosomes affect gene expression. The extremely thermophilic crenarchaeon Sulfolobus has one circular chromosome with three origins of replication.

High-Temperature Live-Cell Imaging of Cytokinesis, Cell Motility, and Cell-Cell Interactions in the Thermoacidophilic Crenarchaeon Sulfolobus acidocaldarius

open access: yesFrontiers in Microbiology, 2021
Significant technical challenges have limited the study of extremophile cell biology. Here we describe a system for imaging samples at 75°C using high numerical aperture, oil-immersion lenses.

First Isolation and Structure Elucidation of GDNT‐β‐Glu – Tetraether Lipid Fragment from Archaeal Sulfolobus Strains

open access: yesChemistryOpen, 2021
Due to their special chemical structure, tetraether lipids (TEL) represent essential elements of archaeal membranes, providing these organisms with extraordinary properties.

Chromosome conformation capture assay combined with biotin enrichment for hyperthermophilic archaea

open access: yesSTAR Protocols, 2021
Summary: Chromosome organization in archaea has long been enigmatic due, in part, to the typically small cell size of archaea and the extremophilic nature of many of the model archaeal species studies, rendering live-cell imaging technically challenging.

Expression, purification, and characterization of a membrane-associated cyclic oligo-adenylate degrader from Sulfolobus islandicus

open access: yesSTAR Protocols, 2021
Summary: Type III CRISPR-cas systems initiate cyclic oligo-adenylate (cOA) signaling to initiate immune response. Previously, we identified that a membrane-associated DHH-DHHA1 family protein from Sulfolobus islandicus efficiently degrades cOA.

High-resolution analysis of chromosome conformation in hyperthermophilic archaea

open access: yesSTAR Protocols, 2021
Summary: Chromosome conformation capture (3C) techniques are emerging as promising approaches to study genome organization in Archaea, the least understood domain of life in terms of chromosome biology. Here, we describe a 3C technique combined with deep

The influence of the specific growth rate on the lipid composition of Sulfolobus acidocaldarius

open access: yesExtremophiles, 2020
Archaeal lipids are constituted of two isoprenoid chains connected via ether bonds to glycerol in the sn-2, 3 position. Due to these unique properties archaeal lipids are significantly more stable against high temperature, low pH, oxidation and enzymatic
