Two membrane-bound transcription factors regulate expression of various type-IV-pili surface structures in Sulfolobus acidocaldarius [PDF]
PeerJ, 2019 In Archaea and Bacteria, gene expression is tightly regulated in response to environmental stimuli. In the thermoacidophilic crenarchaeon Sulfolobus acidocaldarius nutrient limitation induces expression of the archaellum, the archaeal motility structure.

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.

Morphology of the archaellar motor and associated cytoplasmic cone in Thermococcus kodakaraensis [PDF]
Molecular Microbiology, 2017 Archaeal swimming motility is driven by archaella: rotary motors attached to long extracellular filaments. The structure of these motors, and particularly how they are anchored in the absence of a peptidoglycan cell wall, is unknown.

CryoEM reveals the structure of an archaeal pilus involved in twitching motility [PDF]
Nature CommunicationsAmongst the major types of archaeal filaments, several have been shown to closely resemble bacterial homologues of the Type IV pili (T4P). Within Sulfolobales, member species encode for three types of T4P, namely the archaellum, the UV-inducible pilus ...

Characterization of the ATPase FlaI of the motor complex of the Pyrococcus furiosus archaellum and its interactions between the ATP-binding protein FlaH [PDF]
PeerJ, 2018 The archaellum, the rotating motility structure of archaea, is best studied in the crenarchaeon Sulfolobus acidocaldarius. To better understand how assembly and rotation of this structure is driven, two ATP-binding proteins, FlaI and FlaH of the motor ...

Towards a molecular picture of the archaeal cell surface [PDF]
Nature CommunicationsArchaea produce various protein filaments with specialised functions. While some archaea produce only one type of filament, the archaeal model species Sulfolobus acidocaldarius generates four.

MinD proteins regulate CetZ1 localization in Haloferax volcanii [PDF]
Frontiers in MicrobiologyCetZ proteins are archaea-specific homologs of the cytoskeletal proteins FtsZ and tubulin. In the pleomorphic archaeon Haloferax volcanii, CetZ1 contributes to the development of rod shape and motility, and has been implicated in the proper assembly and ...
