The structures of the PII proteins from the cyanobacteria Synechococcus sp. PCC 7942 and Synechocystis sp. PCC 6803
(International Union of Crystallography, 2003)
The PII proteins from the cyanobacteria Synechococcus sp. PCC 7942 and Synechocystis sp. PCC 6803 have been crystallized and high-resolution structures have been obtained using X-ray crystallography. The core of these ...

Structural studies on the synchronization of catalytic centers in glutamate synthase
(American Society for Biochemistry and Molecular Biology, 2002)
The complex iron-sulfur flavoprotein glutamate synthase (GltS) plays a prominent role in ammonia assimilation in bacteria, yeasts, and plants. GltS catalyzes the formation of two molecules of L-glutamate from 2-oxoglutarate ...

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: ...

Characterization of an alcohol dehydrogenase from the cyanobacterium Synechocystis sp. strain PCC 6803 that responds to environmental stress conditions via the Hik34-Rre1 two-component system
(American Society for Microbiology, 2009)
The slr1192 (adhA) gene from Synechocystis sp. strain PCC 6803 encodes a member of the medium-chain alcohol dehydrogenase/reductase family. The gene product AdhA exhibits NADP-dependent alcohol dehydrogenase activity, ...

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. ...

Thioredoxin-linked processes in cyanobacteria are as numerous as in chloroplasts, but targets are different
(National Academy of Sciences, 2003)
Light-dependent regulation of a growing number of chloroplast enzymatic activities has been found to occur through the reversible reduction of intra- or intermolecular disulphides by thioredoxins. In cyanobacteria, despite ...
