Novel Amino Acid Changes Increase Phosphoenolpyruvate Carboxylase Output in planta

Plant, Cell &Environment, Volume 49, Issue 11, Page 8306-8321, November 2026.
ABSTRACT Characterization of previously reported Arabidopsis mutants with increased aluminum (Al) resistance (alr) resulting from greater release of Al‐chelating malate identified three unique amino acid substitutions that each impacts PHOSPHOENOLPYRUVATE CARBOXYLASE 1, a key anaplerotic carbon fixation enzyme.

One Hundred Years of Sulfido Ligand in the Molybdenum Cofactor: New Perspectives

ChemBioChem, Volume 27, Issue 19, 14 October 2026.
The terminal sulfido ligand in mononuclear molybdoenzymes has been appreciated for almost 125 years, with the characterization of Schardinger's enzyme in cow's milk, now known to be xanthine oxidase, that was isolated in 1902 in Vienna, Austria. The ligand is found in molybdoenzymes identified across all kingdoms of life.

Can Non-Conventional Blood Biomarkers Improve Running Performance Prediction? A Proof of Concept

Life
Conventional measures such as maximal oxygen uptake (V˙O2max), although widely regarded as the gold standard, do not fully capture endurance performance.

Establishment and optimization of a novel mouse model of hyperuricemic nephropathy

Renal Failure
Hyperuricemia is a metabolic disorder characterized by elevated serum uric acid levels. Soluble urate can activate immune responses, and the excessive accumulation of urate in the kidneys results in hyperuricemic nephropathy (HN). However, the lack of an

The M. tuberculosis purF::Tn mutant requires exogenous hypoxanthine and thiamine for in vitro growth.

Strains were grown in 7H9 supplemented with 60 μM thiamine and 150 μM hypoxanthine, washed with PBS-T, and diluted to OD600 = 0.05 in 7H9 broth (wild-type and purF::Tn), 7H9 with 150 μM hypoxanthine (purF::Tn +hypoxanthine), or 7H9 with 60 μM thiamine ...
