Structure-Guided Identification of a Small Molecule That Inhibits Anaerobic Choline Metabolism by Human Gut Bacteria

The anaerobic gut microbial pathway that converts choline into trimethylamine (TMA) is broadly linked to human disease. Here, we describe the discovery that betaine aldehyde inhibits TMA production from choline by human gut bacterial isolates and a complex gut community. In vitro assays and a crysta...

description The anaerobic gut microbial pathway that converts choline into trimethylamine (TMA) is broadly linked to human disease. Here, we describe the discovery that betaine aldehyde inhibits TMA production from choline by human gut bacterial isolates and a complex gut community. In vitro assays and a crystal structure suggest betaine aldehyde targets the gut microbial enzyme choline TMA-lyase (CutC). In our system, we do not observe activity for the previously reported CutC inhibitor 3,3-dimethylbutanol (DMB). The workflow we establish for identifying and characterizing betaine aldehyde provides a framework for developing additional inhibitors of gut microbial choline metabolism, including therapeutic candidates.
