The modular architecture of sigma factors in cyanobacteria: a framework to assess their diversity and understand their evolution.

BMC genomics - 24 May 2024

Gevin Marine, Latifi Amel, Talla Emmanuel

Abstract excerpt

BACKGROUND: Bacterial RNA polymerase holoenzyme requires sigma70 factors to start transcription by identifying promoter elements. Cyanobacteria possess multiple sigma70 factors to adapt to a wide variety of ecological niches. These factors are grouped into two categories: primary sigma factor initiates transcription of housekeeping genes during normal growth conditions, while alternative sigma factors initiate...
