Abstract:The biguanide drug metformin is prescribed worldwide as a first-line blood glucose-lowering medication for type 2 diabetes, leading to its presence in the environment around the world. Despite mounting evidence indicating that metabolic interactions of metformin with environmental or intestinal microbes affect ecological and human health, little is known about the fate of metformin by microbial catabolism. Here, we characterized a Ni2+-dependent bacterial enzyme that catalyzes the hydrolysis of metformin to fo… Show more
