Abstract: We constructed a reversed methylotrophic pathway that produces methanol, a promising feedstock for production of useful compounds, from fructose 6-phosphate (F6P), which can be supplied by catabolism of biomass-derived sugars including glucose, by a synthetic biology approach. Using Escherichia coli as an expression host, we heterologously expressed genes encoding methanol utilization enzymes from methylotrophic bacteria, i.e. the NAD⁺-dependent methanol dehydrogenase (MDH) from Bacillus methanolicus S1 and an artificial fusion enzyme of 3-hexulose-6-phosphate synthase and 6-phospho-3-hexuloisomerase from Mycobacterium gastri MB19 (HPS-PHI). We confirmed that these enzymes can catalyze reverse reactions of methanol oxidation and formaldehyde fixation. The engineered E. coli strain co-expressing MDH and HPS-PHI genes produced methanol in resting cell reactions not only from F6P but also from glucose. We successfully conferred reversed methylotrophy to E. coli and our results provide a proof-of-concept for biological methanol production from biomass-derived sugar compounds.
