Genomic responses to arsenic in the cyanobacterium Synechocystis sp. PCC 6803
(Public Library of Science, 2014)
Arsenic is a ubiquitous contaminant and a toxic metalloid which presents two main redox states in nature: arsenite [AsIII] and arsenate [AsV]. Arsenic resistance in Synechocystis sp. strain PCC 6803 is mediated by the ...

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 ...

Metals in Cyanobacteria: Analysis of the Copper, Nickel, Cobalt and Arsenic Homeostasis Mechanisms
(MDPI AG, 2014)
Traces of metal are required for fundamental biochemical processes, such as photosynthesis and respiration. Cyanobacteria metal homeostasis acquires an important role because the photosynthetic machinery imposes a high ...
