Archaeal Cytoskeletal Protein CetZ1 Influences Assembly of the Motility Machinery

open access: yesMolecular 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.

Inteins at Eleven Distinct Insertion Sites in Archaeal Helicase Subunit MCM Exhibit Varied Architectures and Activity Levels Across Archaeal Groups

open access: yesDNA
Background/Objectives: Inteins are mobile genetic elements invading highly conserved genes across all domains of life and viruses. Five active intein insertion sites (MCM-a through e) had previously been identified and studied in the archaeal replicative

Mechanistic Insights into Archaeal and Human Argonaute Substrate Binding and Cleavage Properties.

open access: yesPLoS ONE, 2016
Argonaute (Ago) proteins from all three domains of life are key players in processes that specifically regulate cellular nucleic acid levels.

Dissecting the Repertoire of DNA-Binding Transcription Factors of the Archaeon Pyrococcus furiosus DSM 3638

open access: yesLife, 2018
In recent years, there has been a large increase in the amount of experimental evidence for diverse archaeal organisms, and these findings allow for a comprehensive analysis of archaeal genetic organization.

Archaeal Genes Code for GGDEF Domain Proteins With Diguanylate Cyclase Activity

open access: yesMolecular 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.

Plant genetic and root‐associated microbial diversity modulate Lactuca sativa responsiveness to a soil inoculum under phosphate deficiency

open access: yesNew Phytologist, EarlyView.
Leaf phosphate and shoot biomass variation in response to the microbial consortium. Summary Microbial‐based approaches offer a promising strategy to decrease the use of chemical fertilizers in agriculture. Among them, arbuscular mycorrhizal fungi (AMF), which extend root surface area and enhance phosphate uptake, and phosphate‐solubilizing bacteria ...

Plant NAOGAT (ArgJ) Structure Reveals Mechanism of Ornithine Biosynthesis, Preference for Acetylornithine and Susceptibility to Mangotoxin

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Arginine metabolism in plants is targeted by phytopathogens such as Pseudomonas syringae strains, which produce toxins that affect enzymes of plant arginine metabolism, causing devastating infections in crops. In this work, the structural and functional properties of plant N‐acetylornithine glutamate acetyltransferase (NAOGAT), the key ...

Specificity and Function of Archaeal DNA Replication Initiator Proteins

open access: yesCell Reports, 2013
Chromosomes with multiple DNA replication origins are a hallmark of Eukaryotes and some Archaea. All eukaryal nuclear replication origins are defined by the origin recognition complex (ORC) that recruits the replicative helicase MCM(2-7) via Cdc6 and ...

Universal and Lineage‐Specific Patterns in the Distribution of ECOD Domain Homology Groups Across Superkingdoms

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 10, Page 1644-1657, October 2026.
ABSTRACT Proteins are built from modular domains that serve as fundamental units of structure and evolution. While individual domains have been extensively cataloged, their collective distribution across the lineages of life has remained poorly resolved.
