Archaeal Hel308 suppresses recombination through a catalytic switch that controls DNA annealing (2023)
Journal Article
Lever, R., Simmons, E., Gamble-Milner, R., Buckley, R., Harrison, C., Parkes, A., …Allers, T. (2023). Archaeal Hel308 suppresses recombination through a catalytic switch that controls DNA annealing. Nucleic Acids Research, 51(16), 8563-8574. https://doi.org/10.1093/nar/gkad572

Hel308 helicases promote genome stability in archaea and are conserved in metazoans, where they are known as HELQ. Their helicase mechanism is well characterised, but it is unclear how they specifically contribute to genome stability in archaea. We s...

DNA repair in the archaea: an emerging picture (2018)
Journal Article
White, M. F., & Allers, T. (2018). DNA repair in the archaea: an emerging picture. FEMS Microbiology Reviews, 42(4), 514-526. https://doi.org/10.1093/femsre/fuy020

There has long been a fascination in the DNA Repair pathways of archaea, for two main reasons. Firstly, many archaea inhabit extreme environments where the rate of physical damage to DNA is accelerated. These archaea might reasonably be expected to h...

RadB acts in homologous recombination in the archaeon Haloferax volcanii, consistent with a role as recombination mediator (2017)
Journal Article
Wardell, K., Haldenby, S., Jones, N., Liddell, S., Ngo, G. H., & Allers, T. (2017). RadB acts in homologous recombination in the archaeon Haloferax volcanii, consistent with a role as recombination mediator. DNA Repair, 55, https://doi.org/10.1016/j.dnarep.2017.04.005

Homologous recombination plays a central role in the repair of double-strand DNA breaks, the restart of stalled replication forks and the generation of genetic diversity. Regulation of recombination is essential since defects can lead to genome insta...

High tolerance to self-targeting of the genome by the endogenous CRISPR-Cas system in an archaeon (2017)
Journal Article
Stachler, A.-E., Turgeman-Grott, I., Shtifman-Segal, E., Allers, T., Marchfelder, A., & Gophna, U. (2017). High tolerance to self-targeting of the genome by the endogenous CRISPR-Cas system in an archaeon. Nucleic Acids Research, 45(9), 5208-5216. https://doi.org/10.1093/nar/gkx150

CRISPR-Cas systems allow bacteria and archaea to acquire sequence-specific immunity against selfish genetic elements such as viruses and plasmids, by specific degradation of invader DNA or RNA. However, this involves the risk of autoimmunity if immun... Read More about High tolerance to self-targeting of the genome by the endogenous CRISPR-Cas system in an archaeon.

Production of halophilic proteins using Haloferax volcanii H1895 in a stirred-tank bioreactor (2015)
Journal Article
Strillinger, E., Grötzinger, S. W., Allers, T., Eppinger, J., & Weuster-Botz, D. (2016). Production of halophilic proteins using Haloferax volcanii H1895 in a stirred-tank bioreactor. Applied Microbiology and Biotechnology, 100(3), 1183-1195. https://doi.org/10.1007/s00253-015-7007-1

The success of biotechnological processes is based on the availability of efficient and highly specific biocatalysts, which can satisfy industrial demands. Extreme and remote environments like the deep brine pools of the Red Sea represent highly inte...

DNA damage induces nucleoid compaction via the Mre11-Rad50 complex in the archaeon Haloferax volcanii (2013)
Journal Article
Delmas, S., Duggin, I. J., & Allers, T. (2013). DNA damage induces nucleoid compaction via the Mre11-Rad50 complex in the archaeon Haloferax volcanii. Molecular Microbiology, 87(1), https://doi.org/10.1111/mmi.12091

In prokaryotes the genome is organized in a dynamic structure called the nucleoid, which is embedded in the cytoplasm. We show here that in the archaeon Haloferax volcanii, compaction and reorganization of the nucleoid is induced by stresses that...
