BaiJ and BaiB are key enzymes in the chenodeoxycholic acid 7a-dehydroxylation pathway in the gut microbe Clostridium scindens ATCC 35704

Rizlan Bernier-Latmani, Laure Menin, Karin Lederballe Meibom, Eduard Vico Oton, Théo Nass, Colin Volet, Solenne Anne Marie Marion

Bile acid transformation is a common gut microbiome activity that produces secondary bile acids, some of which are important for human health. One such process, 7α-dehydroxylation, converts the primary bile acids, cholic acid and chenodeoxycholic acid, to ...

Biogeography of microbial bile acid transformations along the murine gut

Rizlan Bernier-Latmani, Laure Menin, Solenne Anne Marie Marion, Lyne Desharnais

Bile acids, which are synthesized from cholesterol by the liver, are chemically transformed along the intestinal tract by the gut microbiota, and the products of these transformations signal through host receptors, affecting overall host health. These tran ...

Biogeography and biochemistry of bile acid 7-dehydroxylation in the mammalian gut

Solenne Anne Marie Marion

Bile acids (BAs) are small molecules synthesized by the host and chemically modified by the microorganisms inhabiting the intestinal tract. The microbial transformation of BAs in the gut is critical to BA-mediated signaling as it modifies their amount and ...
