Phosphorylation of purine and pyrimidine nucleosides by isolated rat liver mitochondria

, 1975
Formation of 5'-AMP, 5'-GMP, 5'-CMP and 5'UMP was confirmed in isolated rat liver mitochondria incubated with alpha-ketoglutarate, inorganic phosphate, purine nucleoside and pyrimidine nucleoside. Increased incorporation of 32Pi into ATP, GTP and UTP was

A Universal Nucleoside‐to‐Nucleoside‐5′‐Triphosphate Enzyme Cascade Driven by Polyphosphate

Angewandte Chemie International Edition, EarlyView.
Nucleoside‐5′‐triphosphates (NTPs) are essential components for the generation of nucleic acids, yet their chemical synthesis is hindered by the low yield of nucleoside phosphorylation. Here, we present a universal, two‐enzyme nucleoside‐to‐NTP cascade that is driven by polyphosphate.

Effect of Cyclic Heat Exposure on the Growth Performance and Metabolism of Broilers Fed Palm Kernel Meal

Animal Research and One Health, EarlyView.
The aim of our study is to evaluate the interaction between HS and the incorporation of PKM in broiler chicken diets, as well as its effect on growth performance and metabolism. Based on the results obtained, PKM supplementation failed to mitigate the adverse effects of heat stress in broiler chickens. ABSTRACT The aim of this study was to evaluate the

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 ...

Characterization of Guanine Deaminase from Kluyveromyces marxianus and Its Industrial Application to Reduce Guanine Content in Beer

Foods
Guanine deaminase (GDA) catalyzes the first step in purine catabolism by converting guanine to xanthine. Despite its significant role in the development of low-purine food, studies on GDA remain limited compared to other metabolic deaminases. To identify

A Metabolomic Signature Predicts Gout Flare Clinical Outcome Associated With Colchicine Prophylaxis

Arthritis &Rheumatology, EarlyView.
Objective This study investigated that serum metabolomics, before urate‐lowering therapy (ULT) initiation, could serve as a biomarker for responsiveness to colchicine prophylaxis in patients with gout commencing treat‐to‐target ULT. Methods We studied a multicenter prospective cohort (n = 409) initiating treat‐to‐target ULT plus colchicine prophylaxis.

Inosine‐Triphosphate‐Pyrophosphatase Activity as a Potential Predictor of Methotrexate Remission in Juvenile Idiopathic Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Methotrexate (MTX) is the first‐line therapy for juvenile idiopathic arthritis (JIA), but up to 40% of patients do not respond to it. Low inosine triphosphate pyrophosphatase (ITPA) activity has been associated with reduced clinical remission. We investigated the role and underlying mechanisms of ITPA in vitro. Methods ITPA enzymatic activity
