Biodesulfurization of Crude Oil Using Locally Isolated Pseudomonas aeruginosa from Oil-Contaminated Soil in Iraqi Kurdistan

Journal of Pure and Applied Microbiology
Locally sourced crude oil from Iraqi Kurdistan contains recalcitrant organosulfur compounds that impair air quality, corrode refinery equipment, and hinder compliance with fuel sulfur regulations. This study isolated a Pseudomonas sp.

4S-Pathway of biodesulfurization of dibenzothiophene (DBT).

, 2018
Four enzymes (DszA, DzsB, DszC and DszD) are involved in the pathway where the first three steps catalyzed by flavin mononucleotide reduced (FMNH2)-dependent monooxygenases, those leading to DBT-sulfoxide (DBTO), DBT-dioxide (DBTO2) and hydroxyphenyl ...

Genetic analysis of benzothiophene biodesulfurization pathway of Gordonia terrae strain C-6. [PDF]

PLoS ONE, 2013
Sulfur can be removed from benzothiophene (BT) by some bacteria without breaking carbon-carbon bonds. However, a clear mechanism for BT desulfurization and its genetic components have not been reported in literatures so far.

Stereoselective cardiovascular toxicity of difenoconazole stereoisomers in zebrafish larvae (Danio rerio) through thyroid hormone disruption

Ecotoxicology and Environmental Safety
Difenoconazole (DIF) is a typical chiral triazole fungicide extensively detected in the environment. This study aimed to explore the stereoselective cardiovascular toxicity of DIF and its four stereoisomers (2S,4S-, 2S,4R-, 2 R,4R-, and 2 R,4S-DIF) in ...

Exploring the electron transfer pathway in the oxidation of avermectin by CYP107Z13 in Streptomyces ahygroscopicus ZB01. [PDF]

PLoS ONE, 2014
Streptomyces ahygroscopicus ZB01 can effectively oxidize 4″-OH of avermectin to form 4″-oxo-avermectin. CYP107Z13 is responsible for this site-specific oxidation in ZB01.

A [4Fe-4S] cluster resides at the active center of phosphomevalonate dehydratase, a key enzyme in the archaeal modified mevalonate pathway

Frontiers in Microbiology, 2023
The recent discovery of the archaeal modified mevalonate pathway revealed that the fundamental units for isoprenoid biosynthesis (isopentenyl diphosphate and dimethylallyl diphosphate) are biosynthesized via a specific intermediate, trans ...

Sertraline Treatment Can Mimic Niemann‐Pick Type C Biomarker Profile: A Diagnostic Pitfall

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Oxysterols (cholestane‐3β,5α,6β‐triol and 7‐ketocholesterol) and N‐palmitoyl‐O‐phosphocholineserine (PPCS) are sensitive biomarkers for Niemann‐Pick disease type C (NPC) screening. However, false‐positive results occur, with a biomarker profile suggestive of NPC despite the absence of pathogenic variants in genes involved in NPC or ...

Mitochondrial Bol1 and Bol3 function as assembly factors for specific iron-sulfur proteins

eLife, 2016
Assembly of mitochondrial iron-sulfur (Fe/S) proteins is a key process of cells, and defects cause many rare diseases. In the first phase of this pathway, ten Fe/S cluster (ISC) assembly components synthesize and insert [2Fe-2S] clusters.

Artificial Intelligence in Systemic Sclerosis: Clinical Applications, Challenges, and Future Directions

Arthritis Care &Research, EarlyView.
Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.
