AglM and VNG1048G, Two Haloarchaeal UDP-Glucose Dehydrogenases, Show Different Salt-Related Behaviors

Life, 2016
Haloferax volcanii AglM and Halobacterium salinarum VNG1048G are UDP-glucose dehydrogenases involved in N-glycosylation in each species. Despite sharing >60% sequence identity and the ability of VNG1048G to functionally replace AglM in vivo, these ...

Structure of a halophilic nucleoside diphosphate kinase from Halobacterium salinarum [PDF]

FEBS Letters, 2005
Nucleoside diphosphate kinase from the halophilic archaeon Halobacterium salinarum was crystallized in a free state and a substrate‐bound form with CDP. The structures were solved to a resolution of 2.35 and 2.2 Å, respectively. Crystals with the apo‐form were obtained with His6‐tagged enzyme, whereas the untagged form was used for co‐crystallization ...

Chromatin and gene regulation in archaea

Molecular Microbiology, Volume 123, Issue 3, Page 218-231, March 2025.
Recent data from diverse archaea with different repertoires of nucleoid‐associated proteins show a common genome‐wide chromatin organisation where chromatin maintains access to gene promoters independently of transcription activity. Abstract The chromatinisation of DNA by nucleoid‐associated proteins (NAPs) in archaea ‘formats’ the genome structure in ...

Regulation of translation in haloarchaea: 5'- and 3'-UTRs are essential and have to functionally interact in vivo [PDF]

, 2009
Recently a first genome-wide analysis of translational regulation using prokaryotic species had been performed which revealed that regulation of translational efficiency plays an important role in haloarchaea.

Archaeal Signalling Networks—New Insights Into the Structure and Function of Histidine Kinases and Response Regulators of the Methanogenic Archaeon Methanosarcina acetivorans

Environmental Microbiology, Volume 27, Issue 2, February 2025.
Methanosarcina acetivorans possesses extensive signal transduction systems, including 53 histidine kinases and 15, mainly REC‐only, response regulators. All recombinant versions of representative kinase types except MA_type 2 showed autokinase activity.

The separation between mRNA‐ends is more variable than expected

FEBS Open Bio, Volume 14, Issue 12, Page 1985-1995, December 2024.
Both mRNA ends are in proximity despite mRNAs origin, length and secondary or tertiary structures. However, we show that the distance between native mRNA ends is not constant and varies across organisms. We found that native sequences show much larger variations than those observed in random sequences, implying the existence of a biological mechanism ...

Ion Transport of Biohybrid Asymmetric Membranes by pH and Light‐Cooperative Modulation

Advanced Materials Interfaces, 2020
Bacteriorhodopsin (bR) is an excellent light‐driven proton pump and plays a vital role in chemical and biological analytical processes, such as maintaining osmotic balance, intracellular acidity, and participating in photosynthesis.

Proteorhodopsin - A new path for biological utilization of light energy in the sea [PDF]

, 2006
The breakthrough of environmental genomics of marine microbes has revealed the existence of eubacterial rhodopsin in the sea, named proteorhodopsin (PR), which can take light to produce bio-energy for cell metabolism.
