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

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.

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 (

Complementation of an aglB Mutant of Methanococcus maripaludis with Heterologous Oligosaccharyltransferases [PDF]
PLoS ONE, 2016 The oligosaccharyltransferase is the signature enzyme for N-linked glycosylation in all domains of life. In Archaea, this enzyme termed AglB, is responsible for transferring lipid carrier-linked glycans to select asparagine residues in a variety of ...

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.

Molecular Microbiology, Volume 116, Issue 3, Page 943-956, September 2021., 2021 KaiC is the central component in the regulation of the cyanobacterial circadian rhythm. KaiC‐like proteins are widespread in archaea, where they are thought to have originated and thought to perform diverse functions. We show that the KaiC‐like protein ArlH—an essential protein for archaeal motility—possesses autophosphorylation activity which mediates

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.
