text: In most other organisms, such as mammals, algae and bacteria, serine is mainly synthesized by the PPSB (Pizer, 1963; Snell, 1984; Melcher and Entian, 1992; Achouri et al., 1997; Dey et al., 2005).
text: In the absence of photorespiration, serine is most likely synthesized either by the glycerate pathway or the PPSB.
text: Thus, serine synthesized by the PPSB might be important to provide one-carbon units for the tetrahydrofolate metabolism and therefore for the synthesis of S-adenosylmethionine, purine and pyrimidine bases in these cells.
text: Therefore, the majority of serine measured in PSAT1-silenced plants is most likely synthesized via photorespiration, whereas serine synthesized by the PPSB might be restricted to few cells only and account for a comparatively small part of the total serine content.
