A Symbiont-Independent Endo-1,4-β-Xylanase from the Plant-Parasitic Nematode Meloidogyne incognita [PDF]

, 2006
Substituted xylan polymers constitute a major part of the hemicellulose fraction of plant cell walls, especially in monocotyledons. Endo-1,4-β-xylanases (EC 3.2.1.8) are capable of hydrolyzing substituted xylan polymers into fragments of random size ...

Computer‐Based Design to Improve Bacillus thuringiensis Chitinase for Industrial Applications

ChemistryOpen, Volume 15, Issue 4, April 2026.
Hotspot‐guided mutagenesis identifies Gly291 as a key catalytic determinant in Bacillus thuringiensis chitinase. Substitution with alanine improves substrate accommodation and lowers the activation barrier by ∼47%, reducing it from 94.66 to 49.83 kcal/mol. Structural integrity is retained while catalytic efficiency is enhanced, demonstrating a rational

Functional metagenomic screening for glycoside hydrolases

, 2017
Limitations on the cultivation of a majority of naturally occurring microbes have spurred the rise of culture-independent methods for the investigation of environmental microbial communities, a field known as metagenomics. This thesis addresses both functional and informatic approaches to metagenomics with the aim of improving our knowledge of ...

Compact tape‐driven sample delivery system for serial femtosecond crystallography

Journal of Applied Crystallography, Volume 59, Issue 2, Page 291-302, April 2026.
A tape‐driven liquid sample droplet delivery system for serial femtosecond crystallography is described.We have developed a compact tape drive (CoT) with on‐demand sample delivery for time‐resolved serial femtosecond crystallography (SFX) experiments, which can deliver sample droplets and/or initiate reactions with a drop‐on‐drop strategy.

Below‐ground drivers of rhizosphere functional gene assembly during Moso bamboo expansion

Functional Ecology, Volume 40, Issue 4, Page 1001-1020, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Moso bamboo (Phyllostachys edulis) expansion threatens subtropical forest biodiversity, yet how intraspecific root trait variation shapes rhizosphere microbial functional potential remains unclear.

Tetraopes Milkweed Beetle Genomes Elucidate the Adaptive Basis of a Temperate Coevolutionary Radiation

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT The coevolutionary radiation of 27 species of Tetraopes longhorned beetles and their Asclepias milkweed hosts represents a classic example of adaptive evolution driven by plant chemical defences and herbivore counteradaptations. Investigations to date, however, have focused on a single species, Tetraopes tetrophthalmus, which feeds on the ...

Environment and Pollen Diversity Differentially Affect the Gut Microbiomes of Introduced Honeybees and Bumblebees

Evolutionary Applications, Volume 19, Issue 4, April 2026.
ABSTRACT Invasive species may exhibit shifts in their gut microbiome in response to novel environments and diet, but this may differ across host species and their time since colonisation. We investigate if site environmental variables and foraged pollen resources differentially shape the gut microbiomes of two bee species with contrasting introduction ...

Transglycosylation by Glycoside Hydrolases - Production and modification of alkyl glycosides [PDF]

, 2015
To enable the transition to a green, bio-based economy, an extensive enzymatic toolbox competitive to traditional chemical procedures is needed. One strong area for enzymes is carbohydrate chemistry, due to the over-functionalized nature of carbohydrates, difficult to handle in traditional chemistry.

Reinventing henna: Enzyme‐catalysed colour release from stabilized Lawsonia inermis L. extracts

International Journal of Cosmetic Science, Volume 48, Issue 2, Page 310-326, April 2026.
The instability and reduced dyeing performance of a cosmetic formulation containing 2‐hydroxy‐1,4‐naphthoquinone (lawsone), derived from Lawsonia inermis L., is demonstrated in comparison to a novel two‐component system. This system comprises one formulation with naturally occurring lawsone precursors and a second containing a specific hydrolase ...

Requirement of group I lytic polysaccharide monooxygenase for turnover of chitinous cuticle during moulting in two forest pest beetles, Monochamus alternatus and Psacothea hilaris

Insect Molecular Biology, Volume 35, Issue 2, Page 115-125, April 2026.
Group I LPMO15‐1 cDNAs from two economically important forest insect pests, M. alternatus and P. hilaris, were cloned. MaLPMO15‐1 and PhLPMO15‐1 show a similar pattern of expression during late stages of development. RNAi for LPMO15‐1 causes failure of adult eclosion in both M. alternatus and P. hilaris.
