Bacillus subtilis HmoB is a heme oxygenase with a novel structure [PDF]

BMB Reports, 2012
Iron availability is limited in the environment and mostbacteria have developed a system to acquire iron from hosthemoproteins. Heme oxygenase plays an important role bydegrading heme group and releasing the essential nutrientiron.

Isolation and characterization of the full-length cDNA encoding a member of a novel cytochrome p450 family (CYP320A1) from the tropical freshwater snail, Biomphalaria glabrata, intermediate host for Schistosoma mansoni [PDF]

, 2005
Cytochrome p450s (cyp450s) are a family of structurally related proteins, with diverse functions, including steroid synthesis and breakdown of toxins. This paper reports the full-length sequence of a novel cyp450 gene, the first to be isolated from the ...

Endogenous Carbon Monoxide Signaling Modulates Mitochondrial Function and Intracellular Glucose Utilization: Impact of the Heme Oxygenase Substrate Hemin

Antioxidants, 2020
Stress-inducible heme oxygenase-1 (HO-1) catalyzes the oxidative cleavage of heme yielding biliverdin, ferrous iron, and carbon monoxide (CO). Heme oxygenase activity has been attributed to antioxidant defense via the redox cycling system of biliverdin ...

2-Oxoglutarate derivatives can selectively enhance or inhibit the activity of human oxygenases

Nature Communications, 2021
The human 2-oxoglutarate (2OG) oxygenases FIH and AspH are relevant drug targets. Here, the authors show that synthetic and naturally occurring 2OG derivatives can selectively modulate FIH and AspH activities, suggesting that these compounds may serve as

Cardiac myocyte-specific knock-out of calcium-independent phospholipase A2γ (iPLA2γ) decreases oxidized fatty acids during ischemia/reperfusion and reduces infarct size [PDF]

, 2016
Calcium-independent phospholipase A(2)γ (iPLA(2)γ) is a mitochondrial enzyme that produces lipid second messengers that facilitate opening of the mitochondrial permeability transition pore (mPTP) and contribute to the production of oxidized fatty acids ...

Characterisation of a Self‐Sufficient Cytochrome P450 Enzyme From the Bacterium Thermosporothrix hazakensis and Its Conversion Into a Peroxygenase

Microbial Biotechnology
The cytochrome P450 monooxygenase enzymes (CYPs) of the CYP102 family are versatile, self‐sufficient biocatalysts. The archetypal example is CYP102A1 (P450BM3) from the bacterium Bacillus (Priestia) megaterium, and variants of this enzyme can oxidise ...

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death

FEBS Open Bio, EarlyView.
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

Hepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

Controlled depolymerization of cellulose by light-driven lytic polysaccharide oxygenases

Nature Communications, 2020
Lytic polysaccharide (mono)oxygenases (LPMOs) perform oxidative cleavage of polysaccharides. Here, the authors showed that the light-driven activity of LPMOs is dependent on hydrogen peroxide availability and can be controlled via the light intensity ...

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

, 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 ...
