Manure amendment and the rhizosphere of Amaranthus hybridus soil bacterial communities in a semi-arid irrigated agroecosystem

Ecosistemas y Recursos Agropecuarios
Soil biodiversity is fundamental to nutrient cycling and ecosystem functioning in agroecosystems, yet the combined effects of organic amendments and weed rhizospheres on soil bacterial communities remain insufficiently explored in semi-arid irrigated ...

Bacterial diversity is positively correlated with soil heterogeneity

Ecosphere, 2018
Plant and animal diversity generally increases with increasing environmental heterogeneity. Here, we test whether this relationship also holds for bacterial communities in soil. Specifically, we investigate whether invasive annual grasslands have reduced

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Bacterial flagellar diversity and significance in pathogenesis [PDF]

FEMS Microbiology Letters, 1992
Bacterial flagella are structurally diverse, ranging from the thoroughly investigated model examples found in Escherichia coli and Salmonella typhimurium to the more exotic sheathed flagella of, for example, Helicobacter pylori, and the complex multi-flagellin endoflagella found in many spirochaetes.

Warming enhances the effects of nitrogen addition on fungal but not on bacterial diversity in an alpine meadow

Basic and Applied Ecology
Warming and nitrogen (N) deposition significantly affect soil microbial community characteristics. However, the responses of bacterial and fungal diversity to warming and N deposition, as well as the dominant influencing factors, remain unclear ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Paenibacillus sp. Strain OL15 Immobilized in Agar as a Potential Bioremediator for Waste Lubricating Oil-Contaminated Soils and Insights into Soil Bacterial Communities Affected by Inoculations of the Strain and Environmental Factors

Biology, 2022
Waste lubricating oil is a widespread common soil pollutant. In this study, the waste lubricating oil degraders were isolated from the oil-contaminated soil.

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

FEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...
