UPO‐Mimetic Engineering of CYP199A4 Enables Enhanced Peroxygenase Activity via the Hydrogen Peroxide Shunt Pathway

open access: yesChemistryEurope, Volume 4, Issue 3, March 2026.
P450 goes peroxide: When one base just isn’t basic enough. Engineering a second basic residue into CYP199A4T252E boosts its peroxygenase activity but also makes it sensitive to H2O2. The double mutant F182R/T252E shows increased turnover before rapidly self‐destructing, revealing the fine balance between productive peroxide activation and oxidative ...

Electrochemical Sensing and Assessment of Parabens in Hydro- Alcoholic Solutions and Water Using a Boron-Doped Diamond Electrode

open access: yesSensors, 2008
In this paper, the electrochemical behaviour of several parabens preservatives, i.e. esters of p-hydroxybenzoic acid, methyl-, ethyl- and propyl-4-hydroxybenzoates as methyl-, ethyl- and propyl-parabens (MB, EB, and PB), has been investigated at a ...

Oxygen Reaction of 4-hydroxybenzoate Monooxygenase

open access: yesZeitschrift für Naturforschung B, 1972
4-hydroxybenzoate hydroxylase from Ps. putida has been studied with regard to the oxygen interaction with the reduced flavin. By rapid scanning spectrophotometry and EPR-measurements of rapidly frozen mixtures no intermediate could be established either in the presence of 4-hydroxybenzoate or the dead-end inhibitor 6-hydroxynicotinic acid.

Engineering 2‐Pyrone‐4,6‐Dicarboxylic Acid Production Reveals Metabolic Plasticity of Poplar

open access: yesPlant Biotechnology Journal, Volume 24, Issue 3, Page 1398-1413, March 2026.
ABSTRACT Woody biomass is a promising source of fermentable sugars for biofuels and bio‐based chemicals, but its industrial use is limited by the costly biorefinery process. A viable strategy to reduce costs involves enhancing both biomass processability and the generation of high‐value co‐products.

Reducing the Sinapine Levels of Camelina sativa Seeds Through Targeted Genome Editing of REF1

open access: yesPlant Biotechnology Journal, Volume 24, Issue 3, Page 1839-1865, March 2026.
ABSTRACT Sinapine (O‐sinapoyl choline) is the major phenolic metabolite typically found in the oil‐rich seeds of Brassicaceae such as Camelina sativa and Brassica napus. It imparts a bitter taste to the seeds as a defence mechanism against herbivores, but it also renders them less palatable to livestock.

Purification and characterization of UDP-glucose: hydroxycoumarin 7-O-glucosyltransferase, with broad substrate specificity from tobacco cultured cells [PDF]

open access: yes, 2000
The enzyme UDP-glucose: hydroxycoumarin 7-O-glucosyltransferase (CGTase), which catalyzes the formation of scopolin from scopoletin, was purified approximately 1200-fold from a culture of 2,4-D-treated tobacco cells (Nicotiana tabacum L. cv.

Electrokinetic potential of some hydroxybenzoic acids and hydroxybenzoic acids-β-glucan models [PDF]

open access: yes, 2020
Hydroxybenzoic acids are subgroup of phenolic acids. 4-hydroxybenzoic acid, gallic acid, vanillic acid, salicylic acid are some of hydroxybenzoic acids. Structure of hydroxybenzoic acids differ because of the hydroxylation and methylations of aromatic ring. β-glucan is soluble dietary fiber constructed of glucose units. Electrokinetic potential is also

Sustainable Porous Carbon Derived from Lignin for High‐Performance CO2 Capture

open access: yesChemistry – An Asian Journal, Volume 21, Issue 4, 25 February 2026.
Lignin‐derived porous carbons offer a sustainable and scalable route for high‐performance CO2 capture. By tailoring ultramicroporosity, hierarchical pore networks, and heteroatom functionalities through chemical activation, templating, and hybrid methods, adsorption capacity and selectivity can be optimized. This review correlates.

4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase in malaria parasites and enhances atovaquone efficacy

open access: yesFEBS Letters, Volume 600, Issue 2, Page 251-266, January 2026.
Atovaquone is an antimalarial requiring potentiation for sufficient efficacy. We pursued strategies to enhance its activity, showing that 4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase, decreasing ubiquinone biosynthesis. Since atovaquone competes with ubiquinol in mitochondria, 4‐nitrobenzoate facilitates its action, potentiating ...
