The Contribution of Plant Dioxygenases to Hypoxia Signaling

open access: yesFrontiers in Plant Science, 2020
Dioxygenases catalyze the incorporation of one or two oxygen atoms into target organic substrates. Besides their metabolic role, these enzymes are involved in plant signaling pathways as this reaction is in several instances required for hormone ...

Variants of the low oxygen sensors EGLN1 and HIF-1AN associated with acute mountain sickness. [PDF]

open access: yes, 2014
Two low oxygen sensors, Egl nine homolog 1 (EGLN1) and hypoxia-inducible factor 1-α inhibitor (HIF-1AN), play pivotal roles in the regulation of HIF-1α, and high altitude adaption may be involved in the pathology of acute mountain sickness (AMS).

Further studies on the substrate spectrum of phytanoyl-CoA hydroxylase

open access: yesJournal of Lipid Research, 2003
Refsum disease is a peroxisomal disorder characterized by adult-onset retinitis pigmentosa, anosmia, sensory neuropathy, ataxia, and an accumulation of phytanic acid in plasma and tissues.

Phylogenomic identification of five new human homologs of the DNA repair enzyme AlkB

open access: yesBMC Genomics, 2003
Background Combination of biochemical and bioinformatic analyses led to the discovery of oxidative demethylation – a novel DNA repair mechanism catalyzed by the Escherichia coli AlkB protein and its two human homologs, hABH2 and hABH3. This discovery was

Reactivity-dependent profiling of RNA 5-methylcytidine dioxygenases

open access: yesNature Communications, 2022
Kleiner and co-workers profile RNA 5-methylcytidine (m5C) dioxygenase enzymes using an activity-based metabolic probing strategy. They reveal ALKBH1 as the major 5-formylcytidine (f5C) writer and characterize modification sites across mRNA and tRNA.

Dioxygen Reactivity of Biomimetic Fe(II) Complexes with Noninnocent Catecholate, \u3cem\u3eo\u3c/em\u3e-Aminophenolate, and \u3cem\u3eo\u3c/em\u3e-Phenylenediamine Ligands [PDF]

open access: yes, 2014
This study describes the O2 reactivity of a series of high-spin mononuclear Fe(II) complexes each containing the facially coordinating tris(4,5-diphenyl-1-methylimidazol-2-yl)phosphine (Ph2TIP) ligand and one of the following bidentate, redox-active ...

Biocatalyst Screening with a Twist: Application of Oxygen Sensors Integrated in Microchannels for Screening Whole Cell Biocatalyst Variants

open access: yesBioengineering, 2018
Selective oxidative functionalization of molecules is a highly relevant and often demanding reaction in organic chemistry. The use of biocatalysts allows the stereo- and regioselective introduction of oxygen molecules in organic compounds at milder ...

Inhibition of DNA methyltransferase leads to increased genomic 5-hydroxymethylcytosine levels in hematopoietic cells. [PDF]

open access: yes, 2018
5-Hydroxymethylcytosine (5hmC) is produced from 5-methylcytosine (5mC) by Ten-eleven translocation (TET) dioxygenases. The epigenetic modification 5hmC has crucial roles in both cellular development and differentiation.

2-oxoglutarate-dependent dioxygenases: A renaissance in attention for ascorbic acid in plants.

open access: yesPLoS ONE, 2020
L-Ascorbic acid (ascorbate, Vitamin C) is an essential human micronutrient that is predominantly obtained from plants. It is known to work as the major antioxidant in plants, and it underpins several environmentally induced stresses due to its use as a ...
