Discovery of a hydrolysis operon in Lachnospiraceae provides a genetic basis to understanding castalagin metabolism by the human microbiome in a clinical study.

Arianna Giurleo, Reilly Pidgeon, Emmanuel Gonzalez…·Bastien Castagner

The paper identifies a hydrolysis operon in Lachnospiraceae that enables castalagin metabolism to urolithins and flavogallonic acid in the human gut microbiome using multi-omics analysis of fecal samples from a clinical trial.

The presence and induction of regioselective dehydroxylases dictate urolithin metabolism by Enterocloster species

Reilly Pidgeon, Arianna Giurleo, Lharbi Dridi, Bastien Castagner

This study identifies a novel urolithin dehydroxylase operon in Enterocloster species and shows its regulation by 9-hydroxy urolithins.

The dietary ellagitannin metabolite urolithin A is produced by a molybdenum-dependent dehydroxylase encoded by prevalent human gut Enterocloster spp.

Reilly Pidgeon, Sacha Mitchell, Michael Shamash…·Bastien Castagner

The paper identifies Enterocloster spp. and the ucd operon as key producers of urolithin A from dietary ellagitannins using multi-omics approaches.
