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.
