Interaction of two strongly divergent archaellins stabilizes the structure of the Halorubrum archaellum [PDF]

MicrobiologyOpen, 2020
Halophilic archaea from the genus Halorubrum possess two extraordinarily diverged archaellin genes, flaB1 and flaB2. To clarify roles for each archaellin, we compared two natural Halorubrum lacusprofundi strains: One of them contains both archaellin ...

Salt‐dependent regulation of archaellins in Haloarcula marismortui [PDF]

MicrobiologyOpen, 2019
Microorganisms require a motility structure to move towards optimal growth conditions. The motility structure from archaea, the archaellum, is fundamentally different from its bacterial counterpart, the flagellum, and is assembled in a similar fashion as

N-Glycosylation Is Important for Halobacterium salinarum Archaellin Expression, Archaellum Assembly and Cell Motility [PDF]

Frontiers in Microbiology, 2019
Halobacterium salinarum are halophilic archaea that display directional swimming in response to various environmental signals, including light, chemicals and oxygen. In Hbt. salinarum, the building blocks (archaellins) of the archaeal swimming apparatus (

Pilin Processing Follows a Different Temporal Route than That of Archaellins in Methanococcus maripaludis [PDF]

Life, 2015
Methanococcus maripaludis has two different surface appendages: type IV-like pili and archaella. Both structures are believed to be assembled using a bacterial type IV pilus mechanism.

Effects of N-glycosylation site removal in archaellins on the assembly and function of archaella in Methanococcus maripaludis. [PDF]

PLoS ONE, 2015
In Methanococcus maripaludis S2, the swimming organelle, the archaellum, is composed of three archaellins, FlaB1S2, FlaB2S2 and FlaB3S2. All three are modified with an N-linked tetrasaccharide at multiple sites.

Decoding the Chemical Language of Ribosomally Synthesized and Post-Translationally Modified Peptides from the Untapped Archaea Domain. [PDF]

Angew Chem Int Ed Engl
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.

Identifying Components of a Halobacterium salinarum N-Glycosylation Pathway [PDF]

Frontiers in Microbiology, 2021
Whereas N-glycosylation is a seemingly universal process in Archaea, pathways of N-glycosylation have only been experimentally verified in a mere handful of species.

Identification of a novel N-linked glycan on the archaellins and S-layer protein of the thermophilic methanogen, Methanothermococcus thermolithotrophicus. [PDF]

J Biol Chem, 2020
Motility in archaea is facilitated by a unique structure termed the archaellum. N-Glycosylation of the major structural proteins (archaellins) is important for their subsequent incorporation into the archaellum filament. The identity of some of these N-glycans has been determined, but archaea exhibit extensive variation in their glycans, meaning that ...

Two types of sheathed archaellum structures from Haloarcula marismortui differ in their outer layer architectures [PDF]

Nature Communications
Many archaea swim by means of rotating helical filaments called archaella. Most archaella are about 10 nm in diameter and comprise multiple copies of the protein archaellin.

TbsP and TrmB jointly regulate gapII to influence cell development phenotypes in the archaeon Haloferax volcanii. [PDF]

Mol Microbiol
The transcription factors TrmB and TbsP coregulate the gluconeogenic enzyme‐coding gene gapII to influence cell lifestyle transitions in hypersaline archaea. The proposed model of regulation is shown above, and the motile‐to‐sessile transition that is indirectly influenced by this regulation is shown below.
