Glutathione Metabolism in M. loti

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


Rhizobium, Bradyrhizobium, Mesorhizobium, Sinorhizobium and Azorhizobium-known as Rhizobia-are Gram-negative, nitrogen-fixing bacteria of agronomic importance because they perform nitrogen-fixing symbiosis with leguminous plants. Nodule formation and the subsequent nitrogen-fixation result from a series of interactions controlled by the exchange of molecular signals between symbiotic bacteria and host plants followed by expression of genes from both symbiotic partners. Mesorhizobium loti is able to form determinant-type globular nodules and perform nitrogen-fixation on several Lotus species (Ref.1, 2 & 3). Glutathione metabolism in M. loti 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 [...]
