Cyanobacteria are photosynthesizing microorganisms that can be used as a model for analyzing gene expression. The expression of genes involves transcription and translation. Transcription is performed by the RNA polymerase (RNAP) holoenzyme, comprising a core enzyme and a sigma (sigma) factor which confers promoter selectivity. The unique structure, expression, and function of cyanobacterial sigma factors (and RNAP core subunits) are summarized here based on studies, reported previously. The typ ...[more]
