Designing and Controlling Transient Supramolecular Gels

open access: yesChemSystemsChem, Volume 7, Issue 2, March 2025.
Designing highly dynamic materials is of great interest to broader systems chemistry. Here a transient gel system which has predetermined changes in state is altered by varying both trigger and temperature, accessing novel materials. The aging of these system is also explored, providing new insights into the control and understanding of supramolecular ...

Structural analysis of the NifL‐NifA complex reveals the molecular basis of anti‐activation of nitrogen fixation gene expression in Azotobacter vinelandii

open access: yesThe FEBS Journal, EarlyView.
Using cryo‐EM combined with biochemical and genetic approaches, we mapped the interaction surface between NifL and NifA to gain insights into the regulation of nitrogen fixation genes in A. vinelandii. Our findings suggest that NifL, a homolog of histidine kinases lacking phosphorylation activity, evolved to act as a steric block of NifA activity ...
