Protein acetylation in archaea, bacteria, and eukaryotes [PDF]

open access: yes, 2010
Proteins can be acetylated at the alpha-amino group of the N-terminal amino acid (methionine or the penultimate amino acid after methionine removal) or at the epsilon-amino group of internal lysines.

Evolutionary rates and gene dispensability associate with replication timing in the Archaeon Sulfolobus islandicus [PDF]

open access: yes, 2010
In bacterial chromosomes, the position of a gene relative to the single origin of replication generally reflects its replication timing, how often it is expressed, and consequently, its rate of evolution.

Collective exchange processes reveal an active site proton cage in bacteriorhodopsin [PDF]

open access: yes, 2020
Proton translocation across membranes is vital to all kingdoms of life. Mechanistically, it relies on characteristic proton flows and modifications of hydrogen bonding patterns, termed protonation dynamics, which can be directly observed by fast magic ...

Desert pavements: A hidden key to Earth surface processes

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.
Desert pavements are a global phenomenon in arid environments, representing one of the most extensive geomorphological and geoecological features on Earth. To a large extent, they determine the interplay of key processes governing current and past landscape dynamics.

Photocycle of halorhodopsin from Halobacterium salinarium

open access: yesBiophysical Journal, 1995
The light-driven chloride pump, halorhodopsin, is a mixture containing all-trans and 13-cis retinal chromophores under both light and dark-adapted conditions and can exist in chloride-free and chloride-binding forms. To describe the photochemical cycle of the all-trans, chloride-binding state that is associated with the transport, and thereby initiate ...

Indigenous Nigerian Vegetables Harbour Plant Species‐Specific Seed Microbial Signatures for Bacteria and Fungi

open access: yesJournal of Sustainable Agriculture and Environment, Volume 4, Issue 4, December 2025.
ABSTRACT Introduction The seed microbiome is essential for plant health, development, and adaptation. Little is known regarding the constituents of seed microbiomes of Africa's indigenous vegetables, which enables the vertical transmission of a specific microbial heritage. Shedding light on this was the focus of the current study.

Structure analysis of biologically important prokaryotic glycopolymers [PDF]

open access: yes, 2013
Of the many post-translational modifications organisms can undertake, glycosylation is the most prevalent and the most diverse. The research in this thesis focuses on the structural characterisation of glycosylation in two classes of glycopolymer (

Functional Specialisation and Diversity Shape the Rhizosphere Microbiota of Cacao and Coffee in the Amazonas Region, Peru

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 6, December 2025.
The microbial species composition, abundance and functional profiles in the rhizospheric soils of cacao and coffee were evaluated. Our findings highlight the presence of predominant but functionally specialised taxa that play unique functional roles within the cacao and coffee rhizosphere ecosystems.

Microbial model of Halobacterium salinarum for screening inhibitors of sterol biosynthesis

open access: yesАнтибиотики и Химиотерапия, 2020
A highly effective and simple microbial test system for screening inhibitors of sterol biosynthesis (ISB) is described. The system is based on cultivation of the bacterial strain Halobacterium salinarum (former Halobacterium halobium), that possesses ...
