Expression and mutational analysis of the glnB genomic region in the heterocyst-forming cyanobacterium anabaena sp. strain PCC 7120
(American Society for Microbiology, 2009)
In the filamentous, heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120, the glnB gene is expressed at considerable levels both in the presence and in the absence of combined nitrogen, although induction, ...

The NtcA-regulated amtB gene is necessary for full methylammonium uptake activity in the cyanobacterium Synechococcus elongatus
(American Society for Microbiology, 2007)
The Amt proteins constitute a ubiquitous family of transmembrane ammonia channels that permit the net uptake of ammonium by cells. In many organisms, there is more than one amt gene, and these genes are subjected to nitrogen ...

The amt gene cluster of the heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2008)
The genome of the heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120 bears a gene cluster including three amt genes that, based on homology of their protein products, we designate amt4, amt1, and amtB. Expression ...
