Expression

Organism Comment Expression
Synechocystis sp. PCC 6803 ggpS mRNA shows a salt-dependent accumulation that roughly follows the kinetics of the intracellular salt ion concentrations in response to salt shocks. The induction of ggpS expression involves several regulatory components in Synechocystis up

General Information

General Information Comment Organism
metabolism the enzyme is synthesized at a basal level under low salt conditions. It is largely inactive and is activated after a salt shock. Since the recombinant enzyme purified from Escherichia coli has NaCl-independent activity, it is concluded that an inhibitor bound to GgpS is removed by NaCl in vivo Synechocystis sp. PCC 6803
