Archaeal Cytoskeletal Protein CetZ1 Influences Assembly of the Motility Machinery

Molecular Microbiology, Volume 126, Issue 4, Page 433-450, October 2026.
The Haloferax volcanii tubulin‐like protein CetZ1 is required for rod‐cell morphogenesis and motility. We show that CetZ1 loss or GTPase inactivation impairs assembly of the motility machinery, including the archaellum base protein ArlD, the chemotaxis adaptor CheW1, and the response regulator CheY.

Haloferax volcanii UbaA, catalytic engine for sampylation and sulfur transfer [PDF]

, 2016
The Small Archaeal Modifier Proteins (SAMPs) from Haloferax volcanii belong to the group of ubiquitin like proteins (Ubls) that act both as protein modifiers and sulfur carriers.

Genetic analysis in Haloferax volcanii.

, 1991
Genetic tools have been developed for studying the molecular biology of the halophilic archaebacterium, Haloferax volcanii. Shuttle vectors and a transformation system facilitate direct cloning of archaebacterial genes, and allow the reintroduction of in

H2‐dependent modulation of tetrahydromethanopterin S‐methyltransferase (Mtr complex) activity by the small protein MtrR in Methanosarcina mazei

The FEBS Journal, Volume 293, Issue 14, Page 4397-4410, July 2026.
Small protein MtrR is a regulator of the Mtr methyltransferase complex in Methanosarcina mazei. It binds specifically to the MtrA subunit and modulates Mtr activity in response to hydrogen (H2) availability. Deleting mtrR impairs growth in the presence but not absence of H2, indicating its role in directing methyl transfer toward an energy‐conserving ...

Perchlorate supported anaerobic growth in Haloferax volcanii reveals a novel metabolic capability with implications for biosignature degradation

Scientific Reports
Haloferax volcanii (H. volcanii) is a facultatively anaerobic model halophilic archaeon capable of anaerobic growth using nitrate, chlorate, fumarate, trimethylamine N-oxide (TMAO), and dimethyl sulfoxide (DMSO) as alternative electron acceptors.

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, Volume 73, Issue 2, Page 913-926, April 2026.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Archaeal Persisters: Persister Cell Formation as a Stress Response in Haloferax volcanii

Frontiers in Microbiology, 2017
Persister cells are phenotypic variants within a microbial population, which are dormant and transiently tolerant to stress. Persistence has been studied extensively in bacteria, and in eukaryotes to a limited extent, however, it has never been observed ...

Lipid Anchoring of Archaeosortase Substrates and Midcell Growth in Haloarchaea

mBio, 2020
The archaeal cytoplasmic membrane provides an anchor for many surface proteins. Recently, a novel membrane anchoring mechanism involving a peptidase, archaeosortase A (ArtA), and C-terminal lipid attachment of surface proteins was identified in the model

Impact of Fire and Heat Stress on Soil Microorganisms: A Review of Community Changes, Molecular Responses and Plant‐Beneficial Roles

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This work reviewed the direct and indirect effects of fires on microbial communities and the resilience strategies microbes use to withstand high temperatures . ABSTRACT Fire, whether occurring on the surface or underground, significantly influences soil microbial dynamics by reshaping community composition, functional diversity and overall soil and ...
