This study shows temperature changes affect PipX interactions in cyanobacteria, revealing PipX as a thermometer for cold shock and demonstrating the NanoBiT system's utility in studying environmental signaling.

The paper uses cryo-EM to study the NifL-NifA complex in Azotobacter vinelandii, revealing how NifL sequesters NifA to regulate nitrogen fixation and enabling engineered strains with enhanced nitrogen secretion.

This study identifies GBP1 as a gene that negatively regulates nitrogen fixation in legumes, showing that its inactivation enhances nitrogen fixation without affecting nodule development.

The paper identifies structural links between nitrogenase-like proteins, LPOR, and chlorophyllide oxidoreductases, revealing their evolutionary origins and functional evolution through structural analysis.
