Opis

Application

The enzyme from Sigma has been used in the analysis of bile samples in various studies.[1][2]

Biochem/physiol Actions

The enzyme is an N-terminal nucleophilic (Ntn) hydrolase that catalyzes the hydrolysis of amide bonds, liberates the glycine/taurine moiety from the steroid core and eventually yields unconjugated bile acids. Agents that oxidize thiol groups (e.g., p-mercuribenzoate, iodoacetamide, Hg²⁺, Cu²⁺, and Cd²⁺) have been shown to strongly inhibit bile salt hydrolase (BSH) activity in Clostridium perfringens.[3]

Physical form

Partially purified lyophilized powder containing buffer salts and stabilizer

Other Notes

One unit will hydrolyze 1.0 μmole of glycocholic acid to glycine and cholic acid in 5 min at pH 5.6 at 37 °C.
