Identification of a Novel Self-Sufficient Styrene Monooxygenase from Rhodococcus opacus 1CP. [PDF]

, 2009
Sequence analysis of a 9-kb genomic fragment of the actinobacterium Rhodococcus opacus 1CP led to identification of an open reading frame encoding a novel fusion protein, StyA2B, with a putative function in styrene metabolism via styrene oxide and ...

Whole cell studies of substrate and inhibitor specificity of isoprene monooxygenase and related enzymes [PDF]

, 2023
Co-oxidation of a range of alkenes, dienes, and aromatic compounds by whole cells of the isoprene-degrading bacterium Rhodococcus sp. AD45 expressing isoprene monooxygenase was investigated, revealing a relatively broad substrate specificity for this ...

Polyphenol Oxidase Activity on Guaiacyl and Syringyl Lignin Units

Angewandte Chemie, Volume 136, Issue 48, November 25, 2024.
The conversion of lignin‐derived guaiacyl (G) and syringyl (S) compounds into methoxy‐ortho‐diphenols through oxidative ortho‐hydroxylation and ortho‐demethoxylation reactions catalyzed by novel fungal polyphenol oxidases (PPOs) is presented. The formation of o‐diphenols rather than reactive quinones can be steered by the addition of a reductant. These

A Mononuclear Scenario for the Copper‐Catalyzed Monooxygenation of Phenolic Substrates

Chemistry – A European Journal, Volume 32, Issue 27, 17 July 2026.
ABSTRACT Whereas a dinuclear pathway applies to the monooxygenation of phenols by the type 3 copper enzyme tyrosinase, a mononuclear pathway has been identified for the same reaction in corresponding small‐molecule systems. DFT calculations of five copper model complexes reveal that the latter mechanism is energetically feasible, identifying all ...

The Biosynthesis and Functions of Flavonoids: Recent Advances From Studies Across Land Plant Diversity

Journal of the Royal Society of New Zealand, Volume 56, Issue 3, June 2026.
Over the last decade there have been significant advances in genome sequencing and model species development for ferns, lycophytes, and the bryophyte lineages—mosses, liverworts, and hornworts. This has facilitated research on the biosynthesis and function of flavonoids in these non‐seed land‐plant lineages.

Oxidative Stress: Molecular Mechanisms, Diseases, and Therapeutic Targets

MedComm, Volume 7, Issue 2, February 2026.
Oxidative stress occurs when the reactive oxygen species (ROS) production overwhelms the ROS scavenging, which lead to genomic instability, epigenetic regulation, proteostasis imbalance, and lipid peroxidation, subsequently causing the occurrence and development of numerous diseases. ABSTRACT Although the physiological level of reactive oxygen species (

Unraveling Lignin's Color Puzzle: From Chromophore Origins to Advanced Decolorization Strategies

Aggregate, Volume 7, Issue 1, January 2026.
This review provides a comprehensive systematic analysis of the research advancements in lignin color formation mechanisms and decolorization techniques, specifically focusing on three principal approaches: hydroxyl shielding, biomass fractionation, and physical methods. It highlights the systematic research approach of the review toward decolorization
