β-Glucuronidase at the gut-liver interface: Structural selectivity, enterohepatic reactivation, and the pharmacomicrobiomic case for precision inhibition.
β-Glucuronidase (β-G, EC 3.2.1.31) reverses phase II glucuronidation, and microbial β-G at the gut-liver interface reactivates biliary and circulating conjugates, closing enterohepatic loops for drugs, estrogens, bile acids, and bilirubin. …
