Fetal growth restriction is associated with placental metabolic adaptations. In small‐for‐gestational‐age placenta (SGA), cholesterol receptors and steroidogenic enzymes are upregulated, enhancing steroidogenesis. NAD salvage pathway is also increased to support NADP+/NADPH requirements.

Insights into the catalytic mechanism of formate dehydrogenases from different microbial sources
This integrated study combines experimental enzyme kinetics with QM/MM simulations to map the catalytic mechanisms of four formate dehydrogenases at the atomic level. This approach reveals the key determinants of catalytic efficiency and guides the rational design of biocatalysts for effective CO2 reduction—a crucial step towards sustainable ...

Human NAD(P)H:quinone oxidoreductase 1 is a homodimeric flavoenzyme crucial for redox metabolism and linked to significant health issues. Point mutations at Tyr126 and Tyr128 demonstrate their essential roles in optimizing substrate binding geometry for catalysis, as well as in half‐site reactivity and conformational dynamics during the enzyme's ...

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen
Serpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,

Arsenite methyltransferase 3 is required for mitochondrial function and hepatic lipid metabolism
AS3MT is a protein that helps the body process arsenic, a naturally occurring toxin found in water and soil. We discovered it also helps cells make and use energy properly. Without AS3MT, cells' mitochondria do not work well, leading to fatty liver and reduced activity. Increasing AS3MT in liver cells restores energy and protects against arsenic damage,
