Synthetic methylotrophy
Disclosed is a microorganism, which has been engineered to acquire methylotrophy. More particularly, the application describes a non-naturally occurring microorganism, which has been engineered to express or include a first enzyme and a second enzyme, wherein the first enzyme is a methanol dehydrogenase (Mdh) enzyme or a methanol oxidase (Mox) enzyme, and wherein the second enzyme is a dihydroxyacetone synthase (Das) enzyme or a transketolase enzyme. The application also describes element and applications, more particularly kits and methods, which include or use the microorganism.
1. A non-naturally occurring microorganism, which has been engineered to acquire methylotrophy, wherein said microorganism comprises a first enzyme and a second enzyme, wherein said first enzyme is a methanol dehydrogenase (Mdh) enzyme, the nucleic acid sequence of which is selected from the group consisting of: SEQ ID NOs: 34-42 and 45,
wherein said second enzyme is a dihydroxyacetone synthase (Das) enzyme, the nucleic acid sequence of which is SEQ ID NO: 47 or 65,
wherein at least one of said first and second enzymes is heterologous to said microorganism, and
wherein the nucleic acid pair of said first enzyme and said second enzyme is selected from the group consisting of SEQ ID NOs: 36 and 47, 37 and 47, 40 and 47, 34 and 65, 35 and 65, 36 and 65, 37 and 65, 38 and 65, 39 and 65, 40 and 65, 41 and 65, 42 and 65, and 45 and 65.
2. The non-naturally occurring microorganism of claim 1 , wherein the nucleic acid pair of said first enzyme and said second enzyme is selected from the group consisting of SEQ ID NOs: 36 and 47, 37 and 47, 40 and 47, 34 and 65, 35 and 65, 36 and 65, 37 and 65, 39 and 65, 41 and 65, and 45 and 65.
3. The non-naturally occurring microorganism of claim 1 , wherein the nucleic acid pair of said first enzyme and said second enzyme is selected from the group consisting of SEQ ID NOS: 35 and 65, and 36 and 65.
4. The non-naturally occurring microorganism of claim 1 , wherein each of said first and second enzymes is heterologous to said microorganism.
5. The non-naturally occurring microorganism of claim 1 , wherein said microorganism is a bacterium, a yeast or a fungus.
6. The non-naturally occurring microorganism of claim 5 , wherein said microorganism is a bacterium, a yeast or a fungus, and wherein
said bacterium is Escherichia, Corynebacterium or Bacillus,
said yeast is Saccharomyces or Pichia , and
said fungus is Yarrowia.
7. The non-naturally occurring microorganism of claim 1 , wherein said first enzyme and said second enzyme are recombinantly expressed from a first nucleic acid and from a second nucleic acid, respectively, and wherein said first and second nucleic acids are either both contained in a same nucleic acid vector or are each contained in separate or different nucleic vectors.
