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

Viscoelastic rotational free convection and coupled heat-mass transfer flow with heat generation and chemical reaction effects

Discover Mechanical Engineering
This work examines the free convection rotational flow of a second-grade (viscoelastic) fluid when a first-order chemical reaction and heat production are present.

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.

Boundary-value analysis of unsteady two-phase MHD Casson dusty fluid flow in a porous channel with Newtonian heating, thermal radiation, and mass diffusion

Boundary Value Problems
The study of non-Newtonian dusty fluids is important due to their applications in cooling systems, nuclear reactors, polymer processing, and particulate transport; however, unsteady two-phase Casson dusty fluid flow in porous channels under the combined ...

Hydrodynamic modeling of deconfinement phase transition in heavy-ion collisions at NICA-FAIR energies

, 2011
We use (3+1) dimensional ideal hydrodynamics to describe the space-time evolution of strongly interacting matter created in Au+Au and Pb+Pb collisions. The model is applied for the domain of bombarding energies 1-160 AGeV which includes future NICA and ...

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.

Flow and coral morphology control coral surface pH: Implications for the effects of ocean acidification

Frontiers in Marine Science, 2016
The future impact of ocean acidification (OA) on corals is disputed in part because mathematical models used to predict these impacts do not seem to capture, or offer a framework to adequately explain, the substantial variability in acidification effects
