Glutathione Metabolism in Z. mobilis

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


Zymomonas mobilis is an ethanologenic microorganism used for the production of fuel ethanol (Ref.1). Glutathione metabolism in Z. mobilis 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. The rate at which Glutathione can be made depends on the availability of Cysteine, which is relatively scarce in foodstuffs. Furthermore, the Cysteine molecule has a sulfur-containing portion which gives the whole Glutathione molecule its ‘biochemical activity’, i.e. its ability to carry out the vitally important functions. Cysteine can also enter the Glutathione metabolism through several other [...]
