Molecular dynamics simulations and fluorescence spectroscopy suggest reduced tryptophan‐to‐heme energy transfer facilitates lignin degradation in ClassII peroxidases

The FEBS Journal, EarlyView.
In lignin peroxidase and versatile peroxidase, low FRET from buried Trp to heme promotes long‐range electron transfer (LRET) from substrate to heme. This efficient electron flow is facilitated by reduced FRET competition. This mechanism likely evolved to enable the effective degradation of bulky, high‐redox‐potential lignin that cannot reach the enzyme'

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology

Geostandards and Geoanalytical Research, EarlyView.
Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Was the Lhasa Block at Low Latitudes in the Middle Permian? Insights From New Paleomagnetic and Geochronological Data

Geophysical Research Letters
The absence of reliable paleomagnetic constraints from the Lhasa Block has led to alternative interpretations of its late Paleozoic position and timing of rifting from Gondwana, reflecting uncertainties in early Neo‐Tethyan paleogeography.
