abstract：:The cyanobacteirum Synechocystis sp. strain PCC 6803 possesses nine species of the sigma (sigma)-factor gene for RNA polymerase (RNAP). Here, we identify and characterize the novel-type promoter recognized by a group 3 sigma-factor, SigF. SigF autoregulates its own transcription and recognizes the promoter of pilA1 th...
