== Function ==
[https://www.uniprot.org/uniprot/CBH_BIFLN CBH_BIFLN] Bile salt hydrolase that catalyzes the deconjugation of glycine- and taurine-linked bile salts, which occurs naturally in the intestines of humans, releasing amino acid residues and deconjugated bile salts (bile acids). Can hydrolyze the amid bond in all six major human bile salts, namely glycocholate (GCA), glycodeoxycholate (GDCA), glycochenodeoxycholate (GCDCA), taurocholate (TCA), taurodeoxycholate (TDCA) and taurochenodeoxycholate (TCDCA). Shows a slight preference for glycine-conjugated bile acids as substrates (PubMed:10831430, PubMed:16905539). Is totally inactive toward penicillin V (PubMed:16905539).<ref>PMID:10831430</ref> <ref>PMID:16905539</ref>

== Publication Abstract from PubMed ==
Bile salt hydrolase (BSH) is an enzyme produced by the intestinal microflora that catalyzes the deconjugation of glycine- or taurine-linked bile salts. The crystal structure of BSH reported here from Bifidobacterium longum reveals that it is a member of N-terminal nucleophil hydrolase structural superfamily possessing the characteristic alphabetabetaalpha tetra-lamellar tertiary structure arrangement. Site-directed mutagenesis of the catalytic nucleophil residue, however, shows that it has no role in zymogen processing into its corresponding active form. Substrate specificity was studied using Michaelis-Menten and inhibition kinetics and fluorescence spectroscopy. These data were compared with the specificity profile of BSH from Clostridium perfrigens and pencillin V acylase from Bacillus sphaericus, for both of which the three-dimensional structures are available. Comparative analysis shows a gradation in activity toward common substrates, throwing light on a possible common route toward the evolution of pencillin V acylase and BSH.
Structural and functional analysis of a conjugated bile salt hydrolase from Bifidobacterium longum reveals an evolutionary relationship with penicillin V acylase.,Kumar RS, Brannigan JA, Prabhune AA, Pundle AV, Dodson GG, Dodson EJ, Suresh CG J Biol Chem. 2006 Oct 27;281(43):32516-25.
