Necromass chemistry drives the functional diversity of the necrobiome, resulting in microbe–organic matter feedbacks

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In temperate European forests, soil fungal communities, dominated by saprotrophic and ectomycorrhizal (ECM) species, represent almost 25% of soil organic carbon (C) in the soil.

Tn‐seq of Thermus thermophilus Genome Reveals Unexpected Tolerance to Insertions in Bacterial Common Essential Genes

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Tn‐seq analysis of Thermus thermophilus genome reveals insertions in almost all genes, this is, there is no clear discrimination of essential genes. A similar result has not been reported in other Tn‐seq analysis of bacterial genomes so far. The polyploidy of the Thermus genome could explain the apparent non‐essentiality of key genes.

Leucine Aminopeptidase in Candida Albicans

Journal of Investigative Dermatology, 1962
Since the late 19th century, there have been numerous publications on proteolytic enzymes in dermatophytes (for literature see 1-5). Bodin (1907), Mallinckrodt-Haupt (1928), and Tate (1929) stated that active proteolytic enzymes (e.g. trypsin, casease, renin, gelatinase (1, 2), or enzymes with activity very similar to trypsin (3)) are present in the ...

ApoJ regulates endothelial lipase activity and stability

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Endothelial lipase (EL) is a key regulator of high‐density lipoprotein (HDL) metabolism. Many aspects of EL function remain incompletely understood due to challenges in purifying active EL. This study identifies apolipoprotein J (ApoJ) as a novel chaperone for EL, crucial for its solubility and activity.

Reduced Dietary Protein Induces Changes in the Dental Proteome

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 2, Page 107-127, March 2026.
Low dietary protein (10%) from normal (20%) does change protein expression in tooth proteome and alter developmental pathways. Among the significant protein expressions changes are actin‐based myosins, tooth, and bone development proteins. Perplexingly tooth size is not altered, suggesting more nuanced phenotypic response to low dietary protein in ...

Clay Minerals Change the Toxic Effect of Cadmium on the Activities of Leucine Aminopeptidase

Adsorption Science & Technology, 2021
Soil leucine aminopeptidase (LAP) is a hydrolytic enzyme involved in the acquisition of nitrogen by microorganisms. In contaminated soils, LAP activity is affected not only by the type and concentration of heavy metals but also by the form of enzyme ...

Functional Divergence of the Arg/N‐Degron Pathway Between the Crop Brassica rapa and the Model Plant Arabidopsis thaliana

Plant Direct, Volume 10, Issue 3, March 2026.
ABSTRACT The ubiquitin‐dependent Arg/N‐degron pathway relates the stability of a substrate protein to the nature of its N‐terminal amino acid residue or its biochemical modifications, with some N‐terminal residues being recognized by specific E3 ubiquitin ligases, resulting in the ubiquitylation and degradation of the substrate protein.

Effects of polystyrene nanoparticles on the microbiota and functional diversity of enzymes in soil

Environmental Sciences Europe, 2018
Background The increasing production of nanoplastics and the fragmentation of microplastics into smaller particles suggest a plausible yet unclear hazard in the natural environment, such as soil.

Photoinactivation and Carbethoxylation of Leucine Aminopeptidase [PDF]

European Journal of Biochemistry, 1975
In the present paper the reactivity of histidyl residues of leucine aminopeptidase from bovine eye lens was studied by dye‐sensitized photooxidation and by carbethoxylation of the enzyme protein using diethylpyrocarbonate.Of all the different amino acids modified by photooxidation only histidine is connected with the enzymic activity, whereas tyrosine ...
