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 thento 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 tothe 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. Also described are engineered cells expressing the
fusion protein, optionally include one or more additional
metabolic pathway transgene(s), methanol
metabolic pathway genes, target product pathway genes,
cell culture compositions including the cells, methods for promoting production of the target product or intermediate thereof from the cells, compositions including the target product or intermediate, and products made from the target product or intermediate.
