Stable isotope metabolomics of pulmonary artery smooth muscle and endothelial cells in pulmonary hypertension and with TGF-beta treatment. [PDF]

, 2020
Altered metabolism in pulmonary artery smooth muscle cells (PASMCs) and endothelial cells (PAECs) contributes to the pathology of pulmonary hypertension (PH), but changes in substrate uptake and how substrates are utilized have not been fully ...

A Genetically Encoded Biosensor for Characterizing Transport and Metabolism of Glutarate

Advanced Science, EarlyView.
Here, a genetically encoded glutarate biosensor, Glusor, is developed based on transcriptional regulator CsiR. Glusor can quantify glutarate concentrations with good accuracy and precision. Then, the role of KgtP and YnfM are identified and characterized by using Glusor. Glusor also allows glutarate spatiotemporal resolution in live cells, facilitating

The Interaction of Glutamate Dehydrogenase and Malate Dehydrogenase with Phospholipid Membranes [PDF]

European Journal of Biochemistry, 1972
The interaction between sonicated dispersions of purified phospholipids, corresponding to those found in the inner mitochondrial membrane, and the enzymes was studied by kinetic and spectroscopic methods.With glutamate dehydrogenase the charge type of the lipid head group determines the extent of lipid‐protein complexing.

On the pathways feeding the H₂ production process in nutrient-replete, hypoxic conditions : commentary on the article 'Low oxygen levels contribute to improve photohydrogen production in mixotrophic non-stressed Chlamydomonas cultures', by Jurado-Oller et al., Biotechnology for Biofuels, published September 7, 2015; 8:149 [PDF]

, 2017
Background: Under low O-2 concentration ( hypoxia) and low light, Chlamydomonas cells can produce H-2 gas in nutrient-replete conditions. This process is hindered by the presence of O-2, which inactivates the [FeFe]-hydrogenase enzyme responsible for H-2

A Refined Adaptive Laboratory Evolution Strategy With Biosensor‐Assisted Selection Resolves the Tolerance–Efficiency Trade‐Off in Toxic Chemical Biosynthesis

Advanced Science, EarlyView.
This study presents a refined adaptive laboratory evolution (ALE) strategy to resolve the trade‐off between tolerance and biosynthetic efficiency in toxic chemical production. Combining in vivo mutagenesis, microdroplet‐based evolution, and biosensor‐assisted selection, this strategy rapidly yields robust “win‐win” phenotypes.

Xylose Metabolism Perturbation in Yarrowia lipolytica for Efficient Succinic Acid Bioproduction from Lignocellulosic Biomass

Advanced Science, EarlyView.
This study engineers Yarrowia lipolytica to produce succinic acid (SA) from lignocellulosic biomass. Adaptive evolution and multi‐omics analysis identify regulators that alleviate xylose metabolic disorder. Multi‐copy integration of xylose metabolic genes resolves redox imbalances from a futile fatty acid cycle, producing high‐titer SA from corn stover
