Rna Later Sigma

Sigma factors are subunits of all bacterial RNA polymerases that are responsible for determining the specificity of promoter DNA binding and efficient initiation of RNA synthesis (transcription) The first sigma factor discovered was the sigma70 (σ 70) of the highly studied bacterium Escherichia coliIts discovery in 1968 was an unexpected result of trying to understand the subunit structure.
