Biological production of adipic acid offers a renewable, lower polluting alternative to the current chemical process. Using lignin-derived monomers as the starting substrate offers economic advantage, but presents a challenge as lignin depolymerization provides a variable monomer stream. Here we show that an enzyme cascade of catechol 1,2-dioxygenase and muconic acid reductase produces adipic acid and adipic acid analogs from catechol and alkyl substituted catechols likely formed during lignin depolymerization. This demonstrates the utility of this enzyme cascade for a variety of lignin-derived feedstocks and the ability to microbially produce adipic acid analogs that can be polymerized to form nylon-like polymers with enhanced properties.

The serotonin receptor 4 (5-HTR4) is expressed throughout the gastrointestinal tract and its agonists are used to treat irritable bowel syndrome with constipation (IBS-C). Today, there are no rapid assays for the identification of 5-HTR4 agonists. Here, we developed a 5-HTR4 assay capable of testing one compound per second and used it to screen >1,000 chemicals. We identified three ligands that are also antibiotics that result in increased colon cell motility. This assay can be used to screen larger pharmaceutical libraries to identify novel treatments for IBS-C. This work shows that antimicrobials interact not only with the gut microbiota, but also with the human host.

Olfactory receptors (ORs) are expressed beyond the olfactory tissue. A key challenge in studying their role is the fact that the majority of ORs are orphaned (i.e. they have no known ligands). We generated sensors for 7 ORs highly expressed in the colon. We ORs against a 57-member chemical panel and successfully deorphanized 2 of them: OR2T4 and OR10S1. We can now start understanding the role of these receptors in the colon.

Microbial production of chemicals relies on the introduction of heterologous enzymes (e.g. from plants) into host organisms (e.g. Escherichia coli). Often, little attention is paid to the interaction between the heterologous and host enzymes. Here, we optimized the interphase of the E. coli's acyl carrier protein (ACP) and Acineyobacter baylyi thioesterase to improve medium-chain fatty acid titers more than 3-fold. Simply engineering the interface between heterologous and host enzymes is a viable strategy to increase chemical titers.

A key limitation in the microbial production of chemicals is the throughput at which strains can be screened for chemical production. Chemical biosensors that convert chemical detection to a fluorescent output can enable high-throughput metabolic engineering applications. Here, we engineered a yeast-based serotonin sensor, used it to detect microbially produced serotonin, and validated it for medium-throughput screening applications.

A number of pharmaceuticals are obtained via chemical derivatization of plant natural products. Today, plant pathways can be reconstituted in microbes and using engineered enzymes. Modified natural products can be produced to more rapidly and cost-effectively access pharmaceuticals. Here, we analyzed more than 2,000 FDA approved drugs and proposed pathways and engineered enzymes to produce modified plant alkaloids to accelerate the semi synthesis of 7 pharmaceuticals on the market.

Anticancer and antimalarial agents are found among plant alkaloids. Isolation of alkaloids from plants is challenging due to their low accumulation and difficult separation from other similar compounds. To become pharmaceuticals, alkaloids often need to be derivatized to increase bioavailability and reduce toxicity. Here, we engineered the first microbial platform for the production of a modified monoterpene indole alkaloid from simple sugars.

Chemical biosensors convert chemical detection to a fluorescent or colorimetric output, enabling the screening of microbially produced chemicals up to 5 orders of magnitude faster than mass spectrometry methods. Here, we developed a platform for the generation of G-protein coupled receptor (GPCR)-based sensors in yeast.
