Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Mining the Genome of Streptomyces leeuwenhoekii: Two New Type I Baeyer–Villiger Monooxygenases From Atacama Desert

Frontiers in Microbiology, 2018
Actinobacteria are an important source of commercial (bio)compounds for the biotechnological and pharmaceutical industry. They have also been successfully exploited in the search of novel biocatalysts.

Accurate and noninvasive prostate cancer detection using plasma‐derived extracellular vesicle RNA

FEBS Open Bio, EarlyView.
Plasma extracellular vesicles were captured with WGA‐conjugated magnetic beads and profiled for RNA biomarkers. A three‐RNA panel (NM_024955, NR_047469, and NR_002564) distinguished prostate cancer from healthy controls and benign prostatic hyperplasia, supporting a simple, noninvasive approach to improve prostate cancer detection.

Immune Modulatory Therapy for Severe Dengue Hemorrhagic Fever in a Patient With Mitochondrial Complex I Deficiency: A Case Report

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Dengue virus (DENV) poses a serious global health challenge, particularly in cases of dengue hemorrhagic fever (DHF). Patients with preexisting mitochondrial disorders may be at increased risk for complications due to the specific impact of DENV on mitochondrial‐dependent cellular processes and immune function.

Using Intrinsic Flavoprotein and NAD(P)H Imaging to Map Functional Circuitry in the Main Olfactory Bulb. [PDF]

PLoS ONE, 2016
Neurons exhibit strong coupling of electrochemical and metabolic activity. Increases in intrinsic fluorescence from either oxidized flavoproteins or reduced nicotinamide adenine dinucleotide (phosphate) [NAD(P)H] in the mitochondria have been used as an ...

Disulfide Bond–Modified Proteomics Reveals the Effects of Riboflavin on Protein Folding Dynamics

Animal Research and One Health, EarlyView.
Riboflavin deficiency impairs oxidative protein folding, causing ER misfolded protein accumulation, CHOP activation, and apoptosis, revealing a role of riboflavin in proteostasis. ABSTRACT Riboflavin is a crucial micronutrient essential for maintaining cellular homeostasis, acting as an important precursor for flavoproteins that utilize flavin ...

D-Amino Acid Oxidase-pLG72 Interaction and D-Serine Modulation

Frontiers in Molecular Biosciences, 2018
pLG72 is a small, primate-specific protein of 153 amino acids. It is the product of the G72 gene, expressed in testis, spinal cord, and brain. The presence of G72 transcript and pLG72 has recurrently been called into question, however G72 mRNA and pLG72 ...

Myocardial inflammation is associated with impaired mitochondrial oxidative capacity in ischaemic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1246-1255, April 2025.
Abstract Aims Myocardial inflammation and impaired mitochondrial oxidative capacity are hallmarks of heart failure (HF) pathophysiology. The extent of myocardial inflammation in patients suffering from ischaemic cardiomyopathy (ICM) or dilated cardiomyopathy (DCM) and its association with mitochondrial energy metabolism are unknown.

Oxidation of amines by flavoproteins [PDF]

Archives of Biochemistry and Biophysics, 2010
Many flavoproteins catalyze the oxidation of primary and secondary amines, with the transfer of a hydride equivalent from a carbon-nitrogen bond to the flavin cofactor. Most of these amine oxidases can be classified into two structural families, the D-amino acid oxidase/sarcosine oxidase family and the monoamine oxidase family.

Stage‐Dependent Metabolic Reprogramming Drives a Self‐Organizing Microbial Network During Shanxi Aged Vinegar

Food Bioengineering, EarlyView.
Metabolic shifts from growth to stress adaptation in Shanxi aged vinegar fermentation link flavor maturation and microbial cooperation, and Lactobacillus and Acetobacter form a self‐organizing metabolic network through division of labor. ABSTRACT Acetic acid fermentation (AAF) is a vital stage in the production of Shanxi aged vinegar (SAV), during ...
