Effects of virus infection on release of volatile organic compounds from insect-damaged bean, Phaseolus vulgaris [PDF]

open access: yes, 2003
Insects can serve as important vectors of plant pathogens, especially viruses. Insect feeding on plants causes the systemic release of a wide range of plant volatile compounds that can serve as an indirect plant defense by attracting natural enemies of ...

Cloning and characterization of the first polysaccharide lyase family 6 oligoalginate lyase from marine Shewanella sp. Kz7.

open access: yesJournal of Biochemistry (Tokyo), 2016
Alginate, the most abundant carbohydrate in brown macroalgae, is widely used in the food and pharmaceutical industries. Recently, alginate has attracted increasing attention, as it may serve as an alternative biomass for the production of biofuel.

Identification of a l‐Threonine‐Utilizing Hydrazine Synthetase for Thrazarine Biosynthesis in Streptomyces coerulescens MH802‐fF5

open access: yesChemBioChem, EarlyView.
A putative thrazarine biosynthetic gene cluster is discovered in the genome sequence of Streptomyces coerulescens MH802‐fF5. In vivo and in vitro analyses of ThzN, a hydrazine synthetase with cupin and methionyl‐tRNA synthetase‐like domains encoded in the cluster, showed that it synthesizes a key intermediate of thrazarine by catalyzing condensation ...

Characterization of AlgMsp, an alginate lyase from Microbulbifer sp. 6532A.

open access: yesPLoS ONE, 2014
Alginate is a polysaccharide produced by certain seaweeds and bacteria that consists of mannuronic acid and guluronic acid residues. Seaweed alginate is used in food and industrial chemical processes, while the biosynthesis of bacterial alginate is ...

Rational Design of Hydrophilic Deep Eutectic Solvents to Outperform Oxidoreductase Activity in Aqueous Media

open access: yesChemCatChem, EarlyView.
This study investigates the catalytic performance of alcohol dehydrogenases (ADHs) — including thermostability, specific activity, and kinetics — in mixtures of glycerol‐based deep eutectic solvents (DESs) and aqueous buffers. By elucidating enzyme—DES interactions, the work identifies the outperforming hydrophilic DESs that enhance redox biocatalysis,

Functional Exploration of the Polysaccharide Lyase Family PL6

open access: yesPLoS ONE, 2016
Alginate, the main cell-wall polysaccharide of brown algae, is composed of two residues: mannuronic acid (M-residues) and, its C5-epimer, guluronic acid (G-residues).

Robust Artificial Polyenzyme for Recyclable Pickering Emulsion and Cascade Synthesis

open access: yesChemCatChem, EarlyView.
Artificial polyenzyme (ArPoly) forms amphiphilic proteinpolymer conjugates that stabilize Pickering emulsions with tunable interfacial properties for biocatalysis. These emulsions enable efficient and robust single‐step reactions, multi‐step biocatalytic cascades, and whole‐cell catalysis.

NRF2 signalling in cytoprotection and metabolism

open access: yesBritish Journal of Pharmacology, EarlyView., 2023
The KEAP1‐NRF2 system plays a central role in cytoprotection in defence mechanisms against oxidative stress. The KEAP1‐NRF2 system has been regarded as a sulfur‐utilizing cytoprotective mechanism, because KEAP1 serves as a biosensor for electrophiles by using its reactive thiols and NRF2 is a transcriptional factor regulating genes involved in sulfur ...
