Structures of Mycobacterium tuberculosis isoprenyl diphosphate synthase Rv2173 in substrate‐bound forms

Acta Crystallographica Section F, Volume 81, Issue 5, Page 193-200, May 2025.
We report the structure of M. tuberculosis isoprenyl diphosphate synthase Rv2173 in three forms, including two with substrate (isoprenyl diphosphate and dimethylallyl diphosphate) occupying the allylic substrate site in different binding poses, with different numbers of metal ions bound.

Changes in leaf economic trait relationships across a precipitation gradient are related to differential gene expression in a C4 perennial grass

New Phytologist, Volume 246, Issue 4, Page 1583-1596, May 2025.
Summary The leaf economics spectrum (LES) describes a suite of functional traits that consistently covary at large spatial and taxonomic scales. Despite its importance at these larger scales, few studies have examined the major drivers of intraspecific variation in the LES – phenotypic plasticity and standing genetic variation.

The role of the LysR‐type transcription factor PacR in regulating nitrogen metabolism in Anabaena sp. PCC7120

Physiologia Plantarum, Volume 177, Issue 3, May/June 2025.
Abstract In the filamentous cyanobacterium Anabaena sp. PCC 7120, heterocyst formation is triggered by changes in the C/N‐ratio and relies on transcriptional reprogramming. The transcription factor PacR is considered a global regulator of carbon assimilation under photoautotrophic conditions, influencing the carbon concentrating mechanism and ...

Frosted DNA: β‐Galactosidase Control of Oligonucleotide Activity

Chemistry – A European Journal, Volume 31, Issue 24, April 25, 2025.
β‐Galactosidase is expressed at low level in many native cells and strongly upregulated in senescent cells. In the present study, we use β‐galactosidase activity as internal trigger to control the hybridization of oligonucleotides–eventually selective in senescent cells. ABSTRACT We introduce a novel approach for the control of oligonucleotides through
