Abstract

The worldwide trend of limiting the use of antibiotic growth promoters (AGPs) in animal production creates challenges for the animal feed industry, thus necessitating the development of effective non‐antibiotic alternatives to improve animal performance. Increasing evidence has shown that the growth‐promoting effect of AGPs is highly correlated with the reduced activity of bile salt hydrolase (BSH, EC 3.5.1.24), an intestinal bacteria‐producing enzyme that has a negative impact on host fat digestion and energy harvest. Therefore, BSH inhibitors may become novel, attractive alternatives to AGPs. Detailed knowledge of BSH substrate preferences and the wealth of structural data on BSHs provide a solid foundation for rationally tailored BSH inhibitor design. This review focuses on the relationship between structure and function of BSHs based on the crystal structure, kinetic data, molecular docking and comparative structural analyses. The molecular basis for BSH substrate recognition is also discussed. Finally, recent advances and future prospectives in the development of potent, safe, and cost‐effective BSH inhibitors are described.

  • N-terminal autocatalysis and oligomeric assembly in homotetramers are critical post-translational modifications to ensure active BSH enzymes.

    “N-terminal autocatalysis and oligomeric assembly in homotetramers are critical post-translational modifications to ensure active BSH enzymes [87].”

    From Bile Salt Hydrolase Activity in the Food-Derived Strain Levilactobacillus brevis M3R3: Genomic and Functional Characterization (2026) · cites this paper as [87]

    The Structural Basis for the Substrate Preference of BSHs section says autocatalytic processing activates the N-terminal catalytic Cys2. The Biochemical Properties and Substrate Preferences of BSHs section says most BSHs are homotetramers, but lists functional enzymes with other oligomeric forms; it does not establish homotetramer assembly as a necessary post-translational modification for activity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
