Abstract

The cysteine synthase complex (CSC) is supposed to regulate the synthesis of cysteine (Cys). This complex is formed by two enzymes: serine acetyltransferase (SAT) and O-acetyl-serine (thiol) lyase (OAS-TL). The CSC occurs within plant cells in three compartments: cytoplasm, chloroplasts and mitochondria. Cys is one of the substrates for the synthesis of glutathione (GSH) – an important player in regulation of redox-state and stress-response in cells. Here we reported influence of light intensity on transgenic tobacco plants with overexpression of active and inactive forms of Arabidopsis thaliana SAT3 targeted to the cytosol.
