Since the substrate (Ru5P) and product (F6P) of the sequential reactions catalyzed by HPS and PHI are intermediates of the Calvin cycle in plants, photosynthesis could provide sufficient substrates for the reactions catalyzed by HPS and PHI if the two enzymes were expressed in plant <i>(Song et al., 2010)</i>. It has been proved that over-expressing the HPS/PHI fusion protein can enhance the ability of the plants to absorb and assimilate exogenous formaldehyde <i>(Chen et al., 2010)</i>. In this case, we utilize the mathematical principles described above to analyze the metabolism.</p> |
