Structure of the SigF1-dependent pilA1 gene promoter and characterization of the light-activated response in the cyanobacterium Synechococcus elongatus PCC 7942
Original language description
In cyanobacteria that perform oxygenic photosynthesis, alternative sigma factors can play critical roles in environmental acclimation at the transcriptional initiation step. Here, we found in tion of the pilA1 gene, encoding the type IV pilin, is dependent on one of the group 3 sigma factors, SigF1. We analyzed the promoter sequence determinants and proposed herein that the10 and35 boxes upstream of the transcriptional start site are critical for transcription. Interestingly, while the pilA1 promoter is activated by illumination, RNA polymerase containing SigF1 is already located on the promoter region under dark conditions, prior to illumination. This strongly suggests that promoter activation by light follows the recruitment of RNA polymerase during transcriptional initiation.
