sigA Type I promoter from Synechocystis sp. PCC 6803
This is the promoter for the sigma factor sigA in Synechocystis sp. PCC 6803. It is self-regulating (controlled by SigA), but has shown to potentially be down-regulated due to changes from heat-shock, darkness, and salt stress. A decrease in SigA protein was observed in a SigC knockout, but not direct proportion to the transcript of SigA (Imamura S and Asayama M. 2009. Sigma Factors for Cyanobacterial Transcription. Gene Regulation and Systems Biology 3:65-87).
As SigA is the housekeeping sigma factor for Synechocystis sp. PCC 6803, this promoter is likely constitutive, with a moderate level of expression (this is pending experimental verification).
