Histamine receptor 2 (HRH2) activation results in gastric acid secretion, and HRH2 blockers are used to treat peptic ulcers.  Some HRH2 blockers decomposes to NDMA, a human carcinogen, in the body. We developed a high-throughput  HRH2-based sensor and use it to identify three novel HRH2 blockers, chlorquinaldol, chloroxine, and broxyquinoline. The blockers share an 8-hydroxyquinoline scaffold, which is not found among known HRH2 blockers. This work demonstrates the utility of GPCR-based sensors for rapid drug discovery applications.

Mars colonization demands technological advances to enable the return of humans to Earth. Shipping the propellant and oxygen for a return journey is not viable. Considering the gravitational and atmospheric differences between Mars and Earth, we propose bioproduction of a Mars-specific rocket propellant, 2,3-butanediol (2,3-BDO), from CO2, sunlight and water on Mars via a biotechnology-enabled in situ resource utilization strategy.

Agonists of the serotonin receptor 4 (5-HTR4) are used to treat irritable bowel syndrome . Here, we developed a 5-HTR4-based sensor capable of testing one compound per second and used it to screen >1,000 chemicals. We identified three antibiotic ligands that result in increased colon cell motility. This assay can be used to screen large pharmaceutical libraries to identify novel treatments for IBS. This work shows that antimicrobials interact not only with the gut microbiota, but also with the human host.

Olfactory receptors are expressed ectopically throughout the body. A key challenge in studying the role of ectopically expressed olfactory receptos (exORs) is the fact that most of them have no known compounds that activate them. We generated sensors for colon exORs  and deorphanized 2 of them. We can now start understanding the role of olfactory receptors in the colon.

Microbial production of chemicals relies on the introduction of enzymes from different organisms into a biotechnology accessible organism, such as Escherichia coli. Often, little attention is paid to the interaction between the heterologous and host enzymes. Here, we optimized the interphase of E. coli‘s acyl carrier protein (ACP) and Acinetobacter baylyi thioesterase to improve medium-chain fatty production.

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 enable high-throughput metabolic engineering applications. Here, we engineer a yeast-based serotonin sensor, used it to detect microbially produced serotonin, and validated the assay for medium-throughput screening applications.

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 approaches.  Here, we developed a platform for the generation of G-protein coupled receptor (GPCR)-based sensors in yeast.
