Nitrate reductase from squash: cDNA cloning and nitrate regulation [PDF]

Proceedings of the National Academy of Sciences, 1986
The assimilation of nitrate in plants involves the reduction of nitrate to ammonia in two steps. The first step requires nitrate reductase, a nitrate-inducible enzyme. When seedlings of squash ( Cucurbita maxima L.) were treated with nitrate, both nitrate reductase activity and protein were induced in the cotyledons.

SNUPN‐Related Muscular Dystrophy: Novel Phenotypic, Pathological and Functional Protein Insights

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective SNUPN‐related muscular dystrophy or LGMDR29 is a new entity that covers from a congenital or childhood onset pure muscular dystrophy to more complex phenotypes combining neurodevelopmental features, cataracts, or spinocerebellar ataxia. So far, 12 different variants have been described.

Oral Dosed Organo‐Silica Nanoparticles Restore Glucose Homeostasis and β‐Cell Function in Diabetes Rats

Advanced Functional Materials, EarlyView.
An oral nanoplatform, MOP@T@D, which can maintain glucose homeostasis and restore islet β cells in diabetic rats is developed. It achieves efficient intestinal absorption and liver‐targeted delivery. The nanoparticle disintegrates only in response to hyperglycemia to release insulin on demand and provides antioxidant protection through selenoprotein ...

Nitrate reductase activity in cabbage (Brassica oleracae var. capitata) seedlings affected by the different nitrogen fertilizer forms

Acta Agrobotanica, 2013
The effect of different nitrogen fertilizer (potassium nitrate, ammonium nitrate, ammonium sulphate, urea and farmyard manure) on nitrate reductase activity in cabbage (Brassica oleracea var. capitata) seedlings were studied.

Analysis of NPF and NRT transporter families regarding the nitrate nutrition in maritime pine (Pinus pinaster) [PDF]

, 2019
Nitrogen is an essential element for life and the main limiting nutrient for plant growth and development1. The main forms of inorganic nitrogen in soils are nitrate and ammonium, which relative abundances depend on environmental conditions such as ...

Doxorubicin‐Loaded Metal–Organic Framework for Ferroptosis‐Enhanced Chemotherapy Through Sustained Zn Release and Glutathione Peroxidase Downregulation

Advanced Healthcare Materials, EarlyView.
A robust zinc‐based metal–organic framework (ZnMOF) enables dual functions of doxorubicin delivery and sustained Zn2+ release to trigger ferroptosis‐enhnaced chemotherapy. DOX@ZnMOF effectively depletes intracellular glutathione, suppresses GPX4, and elevates reactive oxygen species, leading to efficient oxidative DNA damage and apoptosis.

Clustering as a Means To Control Nitrate Respiration Efficiency and Toxicity in Escherichia coli

mBio, 2019
Respiration is a fundamental process that has to optimally respond to metabolic demand and environmental changes. We previously showed that nitrate respiration, crucial for gut colonization by enterobacteria, is controlled by polar clustering of the ...

Molecular Mechanism of 14-3-3 Protein-mediated Inhibition of Plant Nitrate Reductase*

Journal of Biological Chemistry, 2011
Background: Plant nitrate reductase activity is regulated by phosphorylation and subsequent 14-3-3 protein binding. Results: Steady-state and pre-steady kinetics revealed the electron transfer rates between all three redox-active cofactors and identified
