Two membrane-bound transcription factors regulate expression of various type-IV-pili surface structures in Sulfolobus acidocaldarius [PDF]

PeerJ, 2019
In Archaea and Bacteria, gene expression is tightly regulated in response to environmental stimuli. In the thermoacidophilic crenarchaeon Sulfolobus acidocaldarius nutrient limitation induces expression of the archaellum, the archaeal motility structure.

Cellular and Genomic Properties of Haloferax gibbonsii LR2-5, the Host of Euryarchaeal Virus HFTV1

Frontiers in Microbiology, 2021
Hypersaline environments are the source of many viruses infecting different species of halophilic euryarchaea. Information on infection mechanisms of archaeal viruses is scarce, due to the lack of genetically accessible virus–host models. Recently, a new

The Phosphatase PP2A Interacts With ArnA and ArnB to Regulate the Oligomeric State and the Stability of the ArnA/B Complex

Frontiers in Microbiology, 2020
In the crenarchaeon Sulfolobus acidocaldarius, the archaellum, a type-IV pilus like motility structure, is synthesized in response to nutrient starvation. Synthesis of components of the archaellum is controlled by the archaellum regulatory network (arn).

Living electronics: A catalogue of engineered living electronic components

Microbial Biotechnology, Volume 16, Issue 3, Page 507-533, March 2023., 2023
Biology leverages a range of electrical phenomena to extract and store energy, control molecular reactions and enable multicellular communication. Recently, the microbial machinery enabling these redox reactions have been leveraged for interfacing cells and biomolecules with electrical circuits for biotechnological applications.

Putative Extracellular Electron Transfer in Methanogenic Archaea

Frontiers in Microbiology, 2021
It has been suggested that a few methanogens are capable of extracellular electron transfers. For instance, Methanosarcina barkeri can directly capture electrons from the coexisting microbial cells of other species.

Characterization of the ATPase FlaI of the motor complex of the Pyrococcus furiosus archaellum and its interactions between the ATP-binding protein FlaH [PDF]

PeerJ, 2018
The archaellum, the rotating motility structure of archaea, is best studied in the crenarchaeon Sulfolobus acidocaldarius. To better understand how assembly and rotation of this structure is driven, two ATP-binding proteins, FlaI and FlaH of the motor ...

Viral Hijack of Filamentous Surface Structures in Archaea and Bacteria

Viruses, 2021
The bacterial and archaeal cell surface is decorated with filamentous surface structures that are used for different functions, such as motility, DNA exchange and biofilm formation. Viruses hijack these structures and use them to ride to the cell surface

The archaellum: a rotating type IV pilus

Molecular Microbiology, 2014
SummaryMicrobes have evolved sophisticated mechanisms of motility allowing them to respond to changing environmental conditions. While this cellular process is well characterized in bacteria, the mode and mechanisms of motility are poorly understood in archaea.

Surface resistance to SSVs and SIRVs in pilin deletions of Sulfolobus islandicus

Molecular Microbiology, Volume 113, Issue 4, Page 718-727, April 2020., 2020
Evolving SSV9‐resistant Sulfolobus islandicus revealed pilin deletions in host chromosomes that confer broad viral resistance. Pilins were found to be a point of adsorption for Sulfolobus rod‐shaped virus 8, while SSV9 was still able to adsorb, but not infect.

Whole‐genome comparison between the type strain of Halobacterium salinarum (DSM 3754T) and the laboratory strains R1 and NRC‐1

MicrobiologyOpen, Volume 9, Issue 2, February 2020., 2020
The genome of the Halobacterium salinarum type strain (91‐R6, DSM 3754) was compared at the DNA and protein levels to the genomes of two well‐studied laboratory strains, NRC‐1 and R1. The chromosomes and portions of the plasmids were very closely related. However, distinct homologs for proteins involved in motility and N‐glycosylation were encountered.
