Modulation of nitrosative stress by S-nitrosoglutathione reductase is critical for thermotolerance and plant growth in arabidopsis [PDF]

, 2008
Nitric oxide (NO) is a key signaling molecule in plants. This analysis of Arabidopsis thaliana HOT5 (sensitive to hot temperatures), which is required for thermotolerance, uncovers a role of NO in thermotolerance and plant development.

Environmental Identification of Novel Enzymes for Polyurethane and Polyamide Degradation

Angewandte Chemie, EarlyView.
Heteroatom‐containing plastics such as polyurethanes and nylons are produced at scale yet remain largely unrecycled. Biocatalysts offer a promising route to depolymerization under mild conditions. Here, we present a screening platform for the discovery of novel polyurethane‐ and nylon‐degrading enzymes from environmental samples and demonstrate ...

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 ...

Resistant Peanut Genotype Reprograms Rhizosphere Metabolism to Enhance Bacterial Wilt Suppression

Advanced Science, EarlyView.
The resistant peanut genotype selectively recruits beneficial bacteria, which coincides with the activation of salicylic acid (SA)‐dependent systemic acquired resistance (SAR) against Ralstonia solanacearum. Keystone rhizosphere metabolites are positively correlated with both beneficial microbiome assembly and SAR gene expression.

The E3 Ligase RNF115 Aggravates Pathological Cardiac Hypertrophy via Ubiquitin‐Mediated Degradation of SPTBN1

Advanced Science, EarlyView.
In response to hypertrophic stimuli, increased c‑JUN phosphorylation upregulates RNF115, leading to SPTBN1 ubiquitination and degradation. which promotes F‑actin depolymerization and YAP activation, driving cardiac hypertrophy. The RNF115 inhibitor DTD effectively suppresses SPTBN1 ubiquitination and cardiac hypertrophy.

Photooxidative inhibition of nitrate reductase during chilling

, 1982
The effect of a temperature close to the freezing point (chilling) on the nitrate reductase system of leaf discs of Cucumis sativus L. cv. Kleine Groene Scherpe was determined in the absence and presence of light. The capacity of leaf discs in the light (

Design and conduct of 'Xtreme Alps' : a double-blind, randomised controlled study of the effects of dietary nitrate supplementation on acclimatisation to high altitude [PDF]

, 2013
The study of healthy human volunteers ascending to high altitude provides a robust model of the complex physiological interplay that emulates human adaptation to hypoxaemia in clinical conditions.

Nitrate and nitrite reductase activities of Mycobacterium avium

International Journal of Mycobacteriology, 2018
Background: In spite of the fact that the standard test for nitrate reductase activity is negative for Mycobacterium avium, it can grow in a defined minimal medium with either nitrate (NO3) or nitrite (NO2) as sole nitrogen sources.

Conformational Snapshots of CydDC in a Native Lipid Bilayer Coupling Heme Transport to Antibiotic Resistance

Advanced Science, EarlyView.
Phylogenetic and biochemical analyses of the heme transporter CydDC reveal its functional conservation throughout bacterial evolution and demonstrate its unique asymmetric allosteric mechanism. Furthermore, impairment of CydDC function directly affects bacterial antibiotic resistance and likely compromises antibiotic efficacy through drug efflux.

Microbial Reduction of Chromate in the presence of Nitrate by Three Nitrate Respiring Organisms.

Frontiers in Microbiology, 2012
A major challenge for the bioremediation of toxic metals is the co-occurrence of nitrate, as it can inhibit metal transformation. Geobacter metallireducens, Desulfovibrio desulfuricans, and Sulfurospirillum barnesii are three soil bacteria that can ...
