Early picosecond events in the photo cycle of Bacteriorhodopsin [PDF]
, 1986 The primary processes of the photochemical cycle of light-adapted bacteriorhodopsin (BR) were studied by various experimental techniques with a time resolution of 5 × 10-13 s. The following results were obtained.

Transcription start site associated RNAs (TSSaRNAs) are ubiquitous in all domains of life.
PLoS ONE, 2014 A plethora of non-coding RNAs has been discovered using high-resolution transcriptomics tools, indicating that transcriptional and post-transcriptional regulation is much more complex than previously appreciated.

The FEBS Journal, EarlyView.The genes PH0137, PH0138, and PH0140 form a cluster in the genome of Pyrococcus horikoshii. The PH0140 gene encodes a transcription factor identified as a d‐amino acid‐responsive regulatory protein (DARP). In feast mode, l‐Ile‐bound DARP binds to the promoter and represses transcription of PH0137 and PH0138. In famine mode, DARP binds to d‐allo‐Ile and

Halobacterium cutirubrum tRNA sequences [PDF]
FEBS Letters, 1985 The primary structures of nine Halobacterium cutirubrum tRNAs are presented. These tRNAs are compared with other archaebacterial tRNAs and in particular with their H. volcanii counterparts. Striking similarities are observed among isoacceptor tRNA species; observed differences between a given tRNA pair of the two halophiles having the same anticodon ...

Archaeal Cytoskeletal Protein CetZ1 Influences Assembly of the Motility Machinery
Molecular Microbiology, EarlyView.The Haloferax volcanii tubulin‐like protein CetZ1 is required for rod‐cell morphogenesis and motility. We show that CetZ1 loss or GTPase inactivation impairs assembly of the motility machinery, including the archaellum base protein ArlD, the chemotaxis adaptor CheW1, and the response regulator CheY.

Archaeal Genes Code for GGDEF Domain Proteins With Diguanylate Cyclase Activity
Molecular Microbiology, EarlyView.A biofilm‐like mode of growth is hypothesized to be required for the emergence of cellular life. Occurrence of common biofilm gene products in current Bacteria and Archaea is an indication for their previous presence in the last universal common ancestor LUCA and perhaps even in the first universal common ancestor FUCA.

Satellite DNA in Halobacterium Salinarium: A physical and biochemical study [PDF]
, 1970 The extremely halophilic bacterium, Halobacterium salinarium, contains a light density satellite DNA component which is 20% of the total DNA. The purpose of this investigation was to study the physical characteristics of the satellite DNA by ultra ...

Improved Method for Isolation of Photochrome Transmembrane Protein Bacteriorhodopsin from Purple Membranes of Halobacterium Halobacterium Halobium [PDF]
, 2014 This paper presents improved method for isolation of photochrome transmembraine protein bacteriorhodopsin (output 5 mg from 100 g of wet biomass) capable to transform light energy to electrochemical energy of generated protons H+ and ??P. The protein was

Molecular‐Level Modulation of Proton Transport via Electron‐Proton Coupling in Bio‐p‐n Junctions
ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.We developed a pH‐sensing device capable of operating in biological environments. A biohybrid p–n junction was constructed using bacteriorhodopsin (bR) and the photoconductive polymer poly(3‐hexylthiophene) (P3HT). Under light illumination, the photocurrent exhibits distinct transitions across various pH gradients, demonstrating the system's high ...
