    Abstract: Described herein are non-natural NAD+-dependent alcohol dehydrogenases (ADHs) capable of at least two fold greater conversion of methanol or ethanol to formaldehyde or acetaldehyde, respectively, as compared to its unmodified counterpart. Nucleic acids encoding the non-natural alcohol dehydrogenases, as well as expression constructs including the nucleic acids, and engineered cells comprising the nucleic acids or expression constructs are described. Also described are engineered cells expressing a non-natural NAD+-dependent alcohol dehydrogenase, 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.

    Abstract: The invention provides a method of producing acrylic acid. The method includes contacting fumaric acid with a sufficient amount of ethylene in the presence of a cross-metathesis transformation catalyst to produce about two moles of acrylic acid per mole of fumaric acid. Also provided is an acrylate ester. The method includes contacting fumarate diester with a sufficient amount of ethylene in the presence of a cross-metathesis transformation catalyst to produce about two moles of acrylate ester per mole of fumarate diester. An integrated process for process for producing acrylic acid or acrylate ester is provided which couples bioproduction of fumaric acid with metathesis transformation. An acrylic acid and an acrylate ester production also is provided.
