Transcription of glutamine synthetase genes (glnA and glnN) from the cyanobacterium Synechocystis sp. strain PCC 6803 is differently regulated in response to nitrogen availability
(American Society for Microbiology, 1997)
In the cyanobacterium Synechocystis sp. strain PCC 6803 we have previously reported the presence of two different proteins with glutamine synthetase activity: GSI, encoded by the glnA gene, and GSIII, encoded by the glnN ...

The glutathione/glutaredoxin system is essential for arsenate reduction in Synechocystis sp. strain PCC 6803
(American Society for Microbiology, 2009)
Arsenic resistance in Synechocystis sp. strain PCC 6803 is mediated by an operon of three genes in which arsC codes for an arsenate reductase with unique characteristics. Here we describe the identification of two additional ...

Arsenic sensing and resistance system in the cyanobacterium Synechocystis sp. Strain PCC 6803
(American Society for Microbiology, 2003-09)
Arsenic is one of the most important global environmental pollutants. Here we show that the cyanobacterium Synechocystis sp. strain PCC 6803 contains an arsenic and antimony resistance operon consisting of three genes: ...

A new type of glutamine synthetase in cyanobacteria: The protein encoded by the glnN gene supports nitrogen assimilation in Synechocystis sp. strain PCC 6803
(American Society for Microbiology, 1994)
A new glutamine synthetase gene, glnN, which encodes a polypeptide of 724 amino acid residues (M(r), 79,416), has been identified in the unicellular cyanobacterium Synechocystis sp. strain PCC 6803; this is the second gene ...

A gene cluster involved in metal homeostasis in the cyanobacterium Synechocystis sp. strain PCC 6803
(American Society for Microbiology, 2000)
A gene cluster composed of nine open reading frames (ORFs) involved in Ni2+, Co2+, and Zn2+ sensing and tolerance in the cyanobacterium Synechocystis sp. Strain PCC 6803 has been identified. The cluster includes an Ni2+ ...

Light-dependent regulation of cyanobacterial phytochrome expression
(American Society for Microbiology, 2000-01)
A histidine kinase protein (Cph1) with sequence homology and spectral characteristics very similar to those of the plant phytochrome has been recently identified in the cyanobacterium Synechocystis sp. strain PCC 6803. ...

The NADP+-isocitrate dehydrogenase gene (icd) is nitrogen regulated in cyanobacteria
(American Society for Microbiology, 1996)
NADP+-isocitrate dehydrogenase (NADP+-IDH) activity and protein levels in crude extracts from the unicellular cyanobacterium Synechocystis sp. strain PCC 6803 and the filamentous, dinitrogen-fixing Anabaena sp. strain PCC ...
