The method may comprise two steps: (1) hydrating acetylenecarboxylic acid (ACA) or an anion or salt thereof by reacting the ACA or an anion or salt thereof with an ACA-hydrating enzyme to form a reaction product comprising malonic semialdehyde (MSA) or an anion or salt thereof; and (2) reacting the reaction product comprising MSA or an anion or salt thereof with one or more oxidoreductases in an oxidation-reduction (redox) reaction to produce 3-HP or an anion or salt thereof A pair of oxidoreductases may additionally recycle a cofactor, such as NADPH or NADH. Recombinant microbes and compositions are also provided herein which may include ACA-hydrating enzymes or variants thereof, and/or one or more oxidoreductase enzymes.
