Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

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

Organisierte mesoskalige Störungen in der stabilen planetaren Grenzschicht

Meteorologische Zeitschrift, 1995
In der nächtlichen stabilen Grenzschicht treten regelmäßig Störungen mit einer Periodendauer von einigen Stunden auf, deren horizontale Komponenten eine Phasenverschiebung gegeneinander aufweisen, so daß die Hodographen der Windvektoren in einer Höhe ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Sensitivity of ozone production to VOC and NOx emissions — A case study with the box-model BAYROZON

Meteorologische Zeitschrift, 1997
A box-model for the prognosis of tropospheric ozone is used to assess the sensitivity of simulated peak ozone concentrations to local VOC and NOx emissions. Distinction is made between biogenic and anthropogenic emissions.

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.

Determination of photolysis frequencies of ozone and nitrogen dioxide during SANA 2: The influence of tropospheric aerosol particles

Meteorologische Zeitschrift, 1996
Photolysis of ozone and nitrogen dioxide is of vast importance for tropospheric chemistry. Model calculations of photolysis frequencies are available only for cloudless sky and some cases of stratiform cloud cover, whereas direct measurements using ...
