A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

A Three-Level Framework for Assessing and Implementing Environmental Flows

Frontiers in Environmental Science, 2018
In the decade since the Brisbane Declaration (2007) called upon governments and other decision makers to integrate environmental flows into water management, practitioners have continued to seek ways to expand implementation of flow restoration or ...

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Environmental Flows, Political Dams [PDF]

Journal of Political Sciences & Public Affairs, 2013
In 2005, a group of water resource experts issued a statement cajoling decision-makers to privilege the needs of nature in their water management strategies. In effect, their Brisbane Declaration popularized the idea of environmental flows, a concept that focuses attention on the quantity, quality and timing of water required to sustain a dependent ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Agricultural water use accounting provides path for surface water use solutions

California Agriculture, 2020
Agricultural water demands can conflict with habitat needs in many North Coast watersheds. Understanding different water use patterns can help reduce conflict over limited supplies.

Rice Center focuses on restoring wetlands [PDF]

, 2016
Halfway between Richmond and Williamsburg, where Kimages Creek flows into the James River, lies the Inger and Walter Rice Center for Environmental Life Sciences. A restoration project aims to return the area to its original state as a wetland.

Environmental flows - basics for novices [PDF]

, 2016
The term environmental flows has become widely used to define the hydrological regime required to sustain freshwater and estuarine ecosystems and the human livelihoods and well-being that depend on them.
