Haloferax volcanii cells lacking the flagellin FlgA2 are hypermotile [PDF]

Microbiology, 2013
Motility driven by rotational movement of flagella allows bacteria and archaea to seek favourable conditions and escape toxic ones. However, archaeal flagella share structural similarities with bacterial type IV pili rather than bacterial flagella. The Haloferax volcanii genome contains two flagellin genes, flgA1 and flgA2.

Decoding the Chemical Language of Ribosomally Synthesized and Post‐Translationally Modified Peptides from the Untapped Archaea Domain

Angewandte Chemie, Volume 137, Issue 24, June 10, 2025.
Secondary metabolites (SMs) are essential across all life domains, yet those originating from the Archaea domain remain poorly understood. Here, the systematic genome mining and the pioneering heterologous expression of archaeal SMs have revealed the chemical landscape of archaeal lanthipeptides, showing both canonical and non‐canonical forms.

Kleine Zinkfinger-Proteine in Haloferax volcanii [PDF]

, 2021
In der vorliegenden Arbeit wurde das Zinkfinger-µ-Protein HVO_2753 des halophilen Archaeons Haloferax volcanii hinsichtlich seiner biologischen Funktion und seiner Struktur charakterisiert. Zinkfinger-µ-Proteine wurden bisher nur sehr wenig untersucht, während ihnen jedoch in den letzten Jahren steigendes Interesse entgegengebracht wird. Im Genom von H.

In vitro Analysis of Ubiquitin-like Protein Modification in Archaea

Bio-Protocol, 2018
The ubiquitin-like (Ubl) protein is widely distributed in Archaea and involved in many cellular pathways. A well-established method to reconstitute archaeal Ubl protein conjugation in vitro is important to better understand the process of archaeal Ubl ...

Diversity of DNA replication in the archaea [PDF]

, 2017
DNA replication is arguably the most fundamental biological process. On account of their shared evolutionary ancestry, the replication machinery found in archaea is similar to that found in eukaryotes.

RadB acts in homologous recombination in the archaeon Haloferax volcanii, consistent with a role as recombination mediator [PDF]

, 2017
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.

Crystal structures of a halophilic archaeal malate synthase from Haloferax volcanii and comparisons with isoforms A and G [PDF]

, 2011
Background Malate synthase, one of the two enzymes unique to the glyoxylate cycle, is found in all three domains of life, and is crucial to the utilization of two-carbon compounds for net biosynthetic pathways such as gluconeogenesis.

S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

The FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

Archaeal membrane-associated proteases: insights on Haloferax volcanii and other haloarchaea

Frontiers in Microbiology, 2015
The function of membrane proteases range from general house-keeping to regulation of cellular processes. Although the biological role of these enzymes in archaea is poorly understood, some of them are implicated in the biogenesis of the archaeal cell ...
