  • Publication number: 20230265397
    Abstract: Described herein are fusion proteins including methanol dehydrogenase (MeDH) and at least one other polypeptide such as 3-hexulose-6-phosphate dehydrogenase (HPS) or 6-phospho-3-hexuloisomerase (PHI), such as DHAS synthase or fructose-6-Phosphate aldolase or such as DHA synthase or DHA kinase. In a localized manner, the fusion protein can promote the conversion of methanol to formaldehyde and then to a ketose phosphate such as hexulose 6-phosphate or then to DHA and G3P. When expressed in cells, the fusion proteins can promote methanol uptake and rapid conversion to the ketose phosphate or to the DHA and D3P, which in turn can be used in a pathway for the production of a desired bioproduct. Beneficially, the rapid conversion to the ketose phosphate or to the DHA and G3P can avoid the undesirable accumulation of formaldehyde in the cell.

  • Patent number: 10487316
    Abstract: In alternative embodiments, the invention provides phosphatidylinositol-specific phospholipase C (PI-PLC) enzymes, nucleic acids encoding them, antibodies that bind specifically to them, and methods for making and using them. Industrial methods and products comprising use of these phospholipases are also provided. In certain embodiments, provided herein are methods for hydration of non hydratable phospholipids (NHPs) within a lipid matrix. The methods enable migration of NHPs to an oil-water interface thereby allowing the NHPs to be reacted and/or removed from the lipids. In certain embodiments, provided is a method for removing NHPs, hydratable phospholipids, and lecithins from vegetable oils to produce a degummed oil or fat product that can be used for food production and/or non-food applications. In certain embodiments, provided herein are methods for hydration of NHPs followed by enzymatic treatment and removal of various phospholipids and lecithins.

In a localized manner, the fusion protein can promote the conversion of methanol to formaldehyde and then to a ketose phosphate such as hexulose 6-phosphate or then to DHA and G3P. When expressed in cells, the fusion proteins can promote methanol uptake and rapid conversion to the ketose phosphate or to the DHA and D3P, which in turn can be used in a pathway for the production of a desired bioproduct. Beneficially, the rapid conversion to the ketose phosphate or to the DHA and G3P can avoid the undesirable accumulation of formaldehyde in the cell.
