Architectures of archaeal GINS complexes, essential DNA replication initiation factors

BMC Biology, 2011
Background In the early stage of eukaryotic DNA replication, the template DNA is unwound by the MCM helicase, which is activated by forming a complex with the Cdc45 and GINS proteins.

Nanocomposite Reduces Volatile and Aqueous Reactive Nitrogen Losses From Soil Compared to Conventional and Alternative Fertilisers

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Reactive nitrogen losses from agriculture contribute substantially to greenhouse gas emissions, water pollution and ecosystem degradation. Controlled‐release fertiliser technologies offer potential solutions, yet few comprehensively evaluate performance across multiple nitrogen loss pathways and soil types.

Bioinformatic Analysis Reveals Archaeal tRNATyr and tRNATrp Identities in Bacteria

Life, 2017
The tRNA identity elements for some amino acids are distinct between the bacterial and archaeal domains. Searching in recent genomic and metagenomic sequence data, we found some candidate phyla radiation (CPR) bacteria with archaeal tRNA identity for Tyr-

Genetic Features of the Scuticociliate Pathogen Philaster sp. Isolate FWC2 That Causes Sea Urchin Mass Mortality

Journal of Eukaryotic Microbiology, Volume 73, Issue 2, March/April 2026.
ABSTRACT A scuticociliate most closely related to Philaster apodigitiformis caused mass mortalities of diadematoid sea urchins and was cultured as Philaster sp. isolate FWC2. We sequenced the metagenomic content of this isolate, which was predicted to represent ≤ 56% of the complete genome.

Genetic Encoding of a Trifunctional Photo‐Cross‐Linker with a Cleavable Alkyl Ester Moiety

ChemBioChem, Volume 27, Issue 3, February 2026.
A novel noncanonical amino acid, DiZAAsu, possessing photo‐cross‐linking, biotinylation, and alkaline‐cleavable functionalities, is genetically encoded by an engineered pyrrolyl‐tRNA synthetase mutant. The alkyl ester moiety expands the design space of cleavable photo‐cross‐linkable amino acids.

Characterization of an archaeal ubiquitin‐like protein SAMP1

The FASEB Journal, 2013
Small archaeal modifier protein (SAMP1) structurally resembles the eukaryotic ubiquitin (Ub) and bacterial MoaD, sharing with them the β‐grasp fold and C‐terminal GlyGly motif. Our study was aimed to understand the function of SAMP1 using the haloarchaeon Haloferax volcanii as a model system.

Reconstructed ancestral Myo-inositol-3-phosphate synthases indicate that ancestors of the Thermococcales and Thermotoga species were more thermophilic than their descendants.

PLoS ONE, 2013
The bacterial genomes of Thermotoga species show evidence of significant interdomain horizontal gene transfer from the Archaea. Members of this genus acquired many genes from the Thermococcales, which grow at higher temperatures than Thermotoga species ...

Stochasticity Prevails but Differs: Tissue‐Specific Assembly of Gut Microbiomes Across Seasons in an Amphibian Model

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Amphibian gut microbiomes exhibit a temporal‐decay pattern in abundance‐unweighted intercommunity indices rather than abundance‐weighted indices. Stochastic processes play a dominant role in the gut microbiome assembly. Deterministic processes contribute more to large‐intestine microbiomes than to small‐intestine microbiomes.

Structural disorder of plasmid-encoded proteins in Bacteria and Archaea

BMC Bioinformatics, 2018
Background In the last decade and a half it has been firmly established that a large number of proteins do not adopt a well-defined (ordered) structure under physiological conditions.
