Glutathione Metabolism in P. syringae

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


Pseudomonas syringae is a nutritionally versatile organism. The bacterium possesses a large repertoire of transporters for the acquisition of nutrients, particularly sugars, as well as genes implicated in attachment to plant surfaces (Ref.1). There are several pathovars of this bacterium, which are able to cause diseases on various plants. The antagonistic strain is their non-pathogenic counterpart and is antagonistic to pathogens on many plants. It grows well on wounded plant tissue and controls a variety of diseases on different fruits, including pome fruits, banana, and citrus fruits as well as vegetables.

Glutathione is a tripeptide, composed of glutamate, cysteine and glycine, and has numerous important functions within the P. syringae cell. This tripeptide is specifically a thiol compound, present in the [...]
