Gut microbes produce small molecules that enter circulation at pharmacologically relevant levels. At the same time, microbial pathways can compensate for host metabolic deficiencies, demonstrating the microbiome’s dual role as both a modulator and safeguard of human physiology. Despite its importance, the molecular mechanisms underlying these microbial-host metabolic interactions remain poorly understood. In this talk, I will present two recent advances from our lab that bridge this gap. First, we uncovered the 2,8-dioxopurine pathway, a pathway that microbes use to break down purines such as uric acid in the gut. This pathway compensates for the loss of the enzyme uricase during human evolution and shows promise as a new therapy to treat gout, a disease affecting ~50 million adults worldwide. Second, we developed a high-throughput mass spectrometry platform to systematically map microbial metabolism. By screening a bacterial transposon library, we identified more than 40 mutants with distinct metabolic phenotypes, revealing previously unknown metabolic circuits that govern core microbiome functions. Together, these studies demonstrate how decoding microbial metabolism can yield both biological insights and translational opportunities.</font></span></p></span></div></div></div></div></div>
