This study identifies CrsL as a novel transcription factor in Mycobacterium smegmatis that interacts with CarD and regulates gene expression related to stress adaptation.

The paper identifies NAD+ capping in archaeal and mycobacterial organisms, showing its prevalence in stationary phase and involvement of specific promoter elements.

This study identifies HelD as a nucleic acids-clearing factor for RNA polymerase in Mycobacterium smegmatis, revealing its role in recycling RNA polymerase by preventing non-specific DNA interactions and dissociating elongation complexes.

This study shows that dinucleoside polyphosphates function as RNA caps in E. coli, influencing RNA stability and metabolism through incorporation into RNA.

The paper describes the architecture, function, and evolutionary origin of the transcription machinery of yeast killer DNA plasmids, showing similarities to poxviral systems.
