HPS-PHI

The ribulose monophosphate (RuMP) pathway is one of the HCHO-fixation pathways found in microorganisms called methylotrophs, which utilize one-carbon compounds as the sole carbon source. The key enzymes of this pathway are 3-hexulose-6-phosphate synthase (HPS), which fixes HCHO to D-ribulose-5-phosphate (Ru5P) to produce D-arabino-3-hexulose 6-phosphate (Hu6P), and 6-phospho-3- hexuloisomerase (PHI), which converts Hu6P to fructose 6-phosphate (F6P).The two key enzymes work in chloroplast both.We will use fusion expression to conduct heterologous expression in tobacco( Li-mei Chen et al,2010).

Here are some datas from the paper.

Fig.1 Schematic Representation of the Bacterial RuMP Pathway and the Plant Calvin-Benson Cycle. HPS and PHI denote 3-hexulose-6-phosphate synthase and 6-phospho-3-hexuloisomerase respectively. The abbreviations for several sugar phosphates are as follows: Ru5P, ribulose 5-phosphate; Hu6P, hexulose 6-phosphate; F6P, fructose 6-phosphate; FBP, fructose 1,6-bisphosphate;RuBP,ribulose1,5-bisphosphate;3-PGA,3-phosphoglyce-rate. The other metabolites in the pathway are symbolized merely by their carbon numbers for simplicity.

The part BBa_K1537024 contains a fusion gene of HPS and PHI. We created two parts whicich contain HPS and PHI genes seperately. See details on BBa_K3209003 and BBa_K3209004 pages.
