Structure and function of the Si3 insertion integrated into the trigger loop/helix of cyanobacterial RNA polymerase

This study presents the structure of Si3, a unique insertion in cyanobacterial RNA polymerase, and shows it does not affect catalytic activity despite large motion.

RNA polymerase active centre compensates for the absence of transcription proofreading factors in Cyanobacteria

The paper investigates how cyanobacteria compensate for lacking transcription proofreading factors by showing their RNA polymerase actively compensates through structural changes, with trade-offs in regulatory pausing.
