Ruma Banerjee University of Michigan Medical Center Monday, March 26, 2018 - 11:15am Chemistry Building, Room 400 CMS Seminar Toxic at high levels, H2S modulates a range of physiological processes. Biogenesis of H2S synthesis piggybacks on enzymes that catalyze alternative canonical reactions but switch metabolic tracks to meet cellular needs. We will discuss how H2S oxidation and signaling are regulated in colon, which is routinely exposed to high H2S of microbial origin.
