Glutathione Metabolism in Synechocystis sp. PCC6803

This image is a scaled-down version of the actual pathway image. It does not contain any links to the protein information pages.


Synechocystiae are unicellular, photoautotrophic, facultative glucose-heterotrophic bacteria. They are oxygenic photosynthetic with two photosystems at their disposal, similar to those in algae and plants, and they can fix nitrogen. Synechocystis sp. PCC6803 can grow in the absence of photosynthesis if a suitable fixed-carbon source such as glucose is provided. The total length of Synechocystis sp. strain PCC6803 is 3,573,470 bp and it has developed into a Cyanobacterium model (Ref.1 & 2). Glutathione metabolism in Synechocystis sp. involves both the synthesis of Glutathione and its catabolism. Glutathione is a small molecule found in almost every cell. It cannot enter most cells directly and therefore must be made available inside the cell from its three constituent amino acids: Glycine, Glutamate and Cysteine. [...]
