Genomic responses to arsenic in the cyanobacterium Synechocystis sp. PCC 6803.

PloS one - 1 Jan 2014

Sánchez-Riego Ana María, López-Maury Luis, Florencio Francisco Javier

Abstract excerpt

Arsenic is a ubiquitous contaminant and a toxic metalloid which presents two main redox states in nature: arsenite [As(III)] and arsenate [As(V)]. Arsenic resistance in Synechocystis sp. strain PCC 6803 is mediated by the arsBHC operon and two additional arsenate reductases encoded by the arsI1 and arsI2 genes. Here we describe the genome-wide responses to the presence of arsenate and arsenite in wild type and...
