Threonine 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.


Cyanobacteria are photoatutrophic micro-organisms occuring in all photic environments. It is widely accepted that Cyanobacterial type endosymbiont are the ancestor of Chloroplasts in higher plants. Synechocystiae are unicellular, photoautotrophic, facultative glucose-heterotrophic cyanobacteria. They are oxygenic photosynthetic with two photosystems at their disposal, similar to those in Algae and Plants, and they fix atmospheric Nitrogen. Synechocystis sp. PCC6803 grows in the absence of Photosynthesis if a suitable fixed-carbon source such as Glucose is provided. Synechocystis sp. strain PCC6803 is a unicellular Cyanobacterium with a light-dependent cell cycle and contains six to eight chromosome copies (Ref.1). This strain is easily transformable, and capable of growing under phototrophic as well as photoheterotrophic conditions. This strain is naturally transformable by exogenous DNA, and is [...]
