Alr0397 is an outer membrane transporter for the siderophore schizokinen in Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2008)
Iron uptake in proteobacteria by TonB-dependent outer membrane transporters represents a well-explored subject. In contrast, the same process has been scarcely investigated in cyanobacteria. The heterocyst-forming ...

Localized induction of the ntcA regulatory gene in developing heterocysts of Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2006)
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 ...

Role of two NtcA-binding sites in the complex ntcA gene promoter of the heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2008)
Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium that fixes N2 in specialized cells called heterocysts, which differentiate from vegetative cells in a process that requires the nitrogen control transcription ...

Septum-localized protein required for filament integrity and diazotrophy in the heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2007)
Heterocysts, formed when filamentous cyanobacteria, such as Anabaena sp. strain PCC 7120, are grown in the absence of combined nitrogen, are cells that are specialized in fixing atmospheric nitrogen (N2) under oxic conditions ...

Heterocyst development and diazotrophic metabolism in terminal respiratory oxidase mutants of the cyanobacterium Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2007)
Heterocyst development was analyzed in mutants of the heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120 bearing inactivated cox2 and/or cox3 genes, encoding heterocyst-specific terminal respiratory oxidases. ...
