FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Measurements of pernitric acid at the South Pole during ISCAT 2000 [PDF]
, 2002 The first measurements of pernitric acid at the South Pole were performed during the second Investigation of Sulfur Chemistry in the Antarctic Troposphere (ISCAT 2000). Observed HO2NO2 concentrations averaged 25 pptv.

Steady-State Distributions of O2 and OH in the High Atmosphere and Implications in the Ozone Chemistry [PDF]
The Journal of Physical Chemistry A, 2003 Although steady-state distributions are commonly accepted to be of the Boltzmann-type, such an assumption can be rather unrealistic when modeling the high atmosphere. Corroborating evidence is reported for the vibrationaland rotational distributions of O 2 and OH from detailed trajectory calculations, which shows that the thermalization assumption is ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Photochemistry in the arctic free troposphere: NOx budget and the role of odd nitrogen reservoir recycling [PDF]
, 2003 The budget of nitrogen oxides (NOx) in the arctic free troposphere is calculated with a constrained photochemical box model using aircraft observations from the Tropospheric O3 Production about the Spring Equinox (TOPSE) campaign between February and May.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
