A Comprehensive Study of Biohopanoid Production in Alphaproteobacteria: Biosynthetic, Chemotaxonomical, and Geobiological Implications

open access: yesGeobiology, Volume 23, Issue 6, November/December 2025.
ABSTRACT Bacteriohopanepolyol derivatives (BHPDs) and dia‐ and catagenetic products formed from these bacterial membrane modifiers are extensively used as biomarkers in molecular ecological and geoscience studies. Some BHPDs can be assigned to specific phylogenetic bacterial groups. With the vastly increasing availability of complete bacterial genomes,

Lanthanide‐Binding Lanmodulin‐Based Peptides: Insights from Advanced Mass Spectrometry Techniques

open access: yesEuropean Journal of Inorganic Chemistry, Volume 28, Issue 26, September 24, 2025.
Analysis of lanthanide‐binding peptides in the gas phase by advances mass spectrometry methods saves sample amount and time. Selective peptide ligands for lanthanides (Ln) have multiple applications in, for example, Ln‐separation and recycling or as lanthanide‐binding tags.

Interactions of rare earth elements with living organisms and emerging biotechnical applications

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1251-1274, September 2025.
Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

The Elusive Chemistry of Pyrroloquinoline Quinone Dimethyl Ester Lanthanide Complexes in Biomimetic Alcohol Oxidation

open access: yesEuropean Journal of Inorganic Chemistry, Volume 28, Issue 24, August 29, 2025.
Biomimetic complexes of lanthanide‐dependent methanol dehydrogenases bearing a pyrroloquinoline quinone dimethyl ester ligand can oxidize alcohols to aldehydes. Spectroscopic studies on the reaction shed light on the mechanism of the reaction and may explain trends observed in the enzyme.
