  • Publication number: 20220177895
    Abstract: Described herein are engineered cells including ones having synthetic methylotrophy which include an NADH-dependent enzyme capable of converting G3P to 3PG (e.g., B. methanolicus gapN) and/or fructose-1,6-bisphosphatase, along with hexulose-6-phosphate synthase, 6-phospho-3-hexuloisomerase, a phosphoketolase, or a combination thereof. Engineered cells of the disclosure beneficially maintain adequate pool sizes of phosphorylated C3 and/or C4 compounds, and/or provide increased levels of NADPH. As such, the modifications allow for the generation of C6 compounds from C1 (e.g., a methanol feedstod) and C5 compounds, the regeneration of C5 compounds from C6 compounds by carbon rearrangement, and an improved balance between regeneration of C5 compounds and lower glycolysis. In turn, this allows the engineered microorganism to generate sufficient quantities of metabolic precursors (e.g.
