Differential proteomes of the cyanobacterium Cyanothece sp. CCY 0110 upon exposure to heavy metals.

ABSTRACT: The proteomes of the highly efficient extracellular polymeric substances (EPS)-producer cyanobacterium Cyanothece sp. CCY 0110, grown in medium supplemented with an essential metal (Cu(2+)) or a non-essential metal (Cd(2+)),were compared using iTRAQ technology. The data were obtained within a larger study that evaluated the overall effects of different heavy metals on growth/survival, EPS production and ultrastructure of this cyanobacterium [1]. To allow a broader understanding of the strategies triggered to coupe with toxic effects of the metals, Cyanothece's proteomes were evaluated after chronic and acute exposure to Cu(2+) and Cd(2+) in two independent 8-plex iTRAQ studies. For the chronic exposure 0.1 mg/l of Cu(2+) or 5 mg/l of Cd(2+) were used for 10 and 20 days, while in the acute
