Phylogenetic and genomic analyses of the ribosomal oxygenases Riox1 (No66) and Riox2 (Mina53) provide new insights into their evolution

open access: yesBMC Evolutionary Biology, 2018
Background Translation of specific mRNAs can be highly regulated in different cells, tissues or under pathological conditions. Ribosome heterogeneity can originate from variable expression or post-translational modifications of ribosomal proteins.

Heme Oxygenase-Like Metalloenzymes. [PDF]

open access: yesAnnu Rev Biochem
Heme oxygenase (HO)-like metalloenzymes are an emerging protein superfamily diverse in reaction outcome and mechanism. Found primarily in bacterial biosynthetic pathways, members conserve a flexible protein scaffold shared with the heme catabolic enzyme, HO, and a set of metal-binding residues.

Adenosine monophosphate–activated protein kinase activation is associated with suppression of NLRP3 inflammasome–mediated neuroinflammation in a weight‐drop model of traumatic brain injury in Sprague–Dawley rats

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This graphical abstract illustrates the study's schematic model. Adenosine monophosphate–activated protein kinase (AMPK) activators exhibited neuroprotection in the weight‐drop model of traumatic brain injury by improving cognition and regulating oxidative stress, microglial activation, and nucleotide‐binding oligomerization domain, leucine‐rich repeat,

Characterized cis-FeV(O)(OH) intermediate mimics enzymatic oxidations in the gas phase

open access: yesNature Communications, 2019
FeV(O)(OH) species have long been thought to play a role in a range of enzymatic oxidations, but their characterization has remained elusive. Here, using gas-phase ion spectroscopy, the authors characterize an FeV(O)(OH) species and find that its ...

Fatty acid oxygenase activity of human hair roots

open access: yesJournal of Lipid Research, 1993
The extent to which fatty acid oxygenases are activated in the normal epidermis is not known. Characterization of the regio- and stereospecificity of the monohydroxylated derivatives of arachidonic and linoleic acid produced by human hair roots is needed

Oxygenase Coordination Is Required for Morphological Transition and the Host–Fungus Interaction of Aspergillus flavus

open access: yesMolecular Plant-Microbe Interactions, 2009
Oxylipins, a class of oxygenase-derived unsaturated fatty acids, are important signal molecules in many biological systems. Recent characterization of an Aspergillus flavus lipoxygenase gene, lox, revealed its importance in maintaining a density ...

An all‐in‐one fucosylated gold nanocluster probe enables NIR‐II imaging and multi‐mechanistic therapy of acute kidney injury

open access: yesBMEMat, EarlyView.
This study developed a fucoside‐targeted gold nanocluster probe that enables early NIR‐II imaging and multi‐mechanistic therapy for acute kidney injury, effectively mitigating oxidative stress, modulating inflammatory responses, and inhibiting ferroptosis to improve renal outcomes. Abstract Acute kidney injury (AKI) remains a life‐threatening condition

Heat stress in spermatogenesis: a redox‐dependent decision network linking ROS, autophagy, and regulated cell death

open access: yesBiological Reviews, EarlyView.
ABSTRACT Heat stress (HS) is an increasing threat to male reproductive health, disrupting spermatogenesis through complex and interdependent cellular responses within the seminiferous epithelium. Although excessive reactive oxygen species (ROS) production is a hallmark of HS, ROS also act as central regulators of cell fate decisions beyond their role ...

Mechanism of Isonitrilase, a Nonheme Iron Decarboxylase Involved in the Biosynthesis of the Isonitrile Group in Peptides: A Computational Study

open access: yesChemistry – A European Journal, EarlyView.
A combination of molecular dynamics and quantum mechanics calculations shows that substrate is tightly bound inside the enzyme structure that enables two successive catalytic cycles with dioxygen and α‐ketoglutarate with an initial desaturation followed by hydrogen abstraction and decarboxylation steps to form an isonitrile substituent.
