Temperature changes are signaled in cyanobacteria through the PipX interaction network

Antonio Llop, Sirine Bibak, Trinidad Mata‐Balaguer, Lorena Tremiño, Laura Fuertes-García, José L. Neira, Ray A. Dixon, Asunción Contreras

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.

Structures of the cyanobacterial nitrogen regulators NtcA and PipX complexed to DNA fully clarify DNA binding by NtcA and recruitment of RNA polymerase by PipX

Alicia Forcada‐Nadal, Sirine Bibak, Paloma Salinas, Asunción Contreras, Vicente Rubio, J. L. Llacer

This study determines the structures of NtcA and PipX complexes with DNA, revealing how NtcA binds DNA specifically and how PipX stabilizes NtcA's active conformation and recruits RNA polymerase.
