Localized induction of the ntcA regulatory gene in developing heterocysts of Anabaena sp. strain PCC 7120

The ntcA gene encodes an N-control transcriptional regulator in cyanobacteria. In the N2-fixing, heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120, ntcA is an autoregulatory gene that is transcribed from a complex promoter region that includes a constitutive promoter (P 2) and promoters...
