Abstract: Provided herein, inter alia, are methods, host cells, and vectors for producing 3-hydroxypropionate (3-HP). In some embodiments, the host cells include a recombinant polynucleotide encoding an oxaloacetate decarboxylase (OAADC) and a polynucleotide encoding a 3-hydroxypropionate dehydrogenase (3-HPDH). In some embodiments, the methods include culturing said host cell(s) in a culture medium comprising a substrate under conditions suitable for the recombinant host cell to convert the substrate to 3-HP. Expression of the OAADC and the 3-HPDH results in increased production of 3-HP, as compared to production by a host cell lacking expression of the OAADC and the 3-HPDH.

Abstract: Protein dimers that are modified to detect plant hormones are provided. In some embodiments, a protein dimer is provided comprising a first amino acid sequence and a second amino acid sequence, wherein the protein dimer dissociates in the presence of a plant hormone and the dissociation results in a detectable signal.

Abstract: Provided herein are engineered polypeptides that exhibit increased catalytic efficiency for unnatural cofactors and use of said polypeptides in engineered unnatural redox cofactor systems for whole-cell biomanufacturing and in cell-free applications.
