Proposed Role for KaiC-Like ATPases as Major Signal Transduction Hubs in Archaea
mBio, 2017 All organisms must adapt to ever-changing environmental conditions and accordingly have evolved diverse signal transduction systems. In bacteria, the most abundant networks are built around the two-component signal transduction systems that include ...

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 ...

High‐resolution archaellum structure reveals a conserved metal‐binding site
EMBO reports, 2019 Many archaea swim by means of archaella. While the archaellum is similar in function to its bacterial counterpart, its structure, composition, and evolution are fundamentally different. Archaella are related to archaeal and bacterial type IV pili.

Decipering the subunit interaction in the crenarchaeal archaellum
, 2014 The archaeal motility structure, the archaellum is an intriguing hybrid of the function and architecture of two distinct motility organelles, the bacterial flagellum and the T4P, respectively. This rotating T4P is an astonishing example of evolutionary adaptation and represents indeed a unique, third way to move.

FlaF Is a β-Sandwich Protein that Anchors the Archaellum in the Archaeal Cell Envelope by Binding the S-Layer Protein [PDF]
Structure, 2015 Archaea employ the archaellum, a type IV pilus-like nanomachine, for swimming motility. In the crenarchaeon Sulfolobus acidocaldarius, the archaellum consists of seven proteins: FlaB/X/G/F/H/I/J. FlaF is conserved and essential for archaellum assembly but no FlaF structures exist.

DIVERSITY AND EVOLUTION OF TYPE IV PILI SYSTEMS IN ARCHAEA
Frontiers in Microbiology, 2016 Many surface structures in archaea including various types of pili and the archaellum (archaeal flagellum) are homologous to bacterial type IV pili systems (T4P).

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.

MicrobiologyOpen, 2016 Expression of the archaellum, the archaeal-type IV pilus-like rotating motility structure is upregulated under nutrient limitation. This is controlled by a network of regulators, called the archaellum regulatory network (arn). Several of the components of this network in Sulfolobus acidocaldarius can be phosphorylated, and the deletion of the ...

Horizontal gene transfer of the functional archaellum machinery to Bacteria
Motility in Archaea is driven by a nanomachinery called the archaellum. So far, archaella have been exclusively described for the archaeal domain; however, a recent study reported the presence of archaellum gene clusters in bacterial strains of the SAR202 clade (Chloroflexota).
