In enzymology, a choloylglycine hydrolase () is an enzyme that catalyzes the chemical reaction 3alpha,7alpha,12alpha-trihydroxy-5beta-cholan-24-oylglycine + H2O 3alpha,7alpha,12alpha-trihydroxy-5beta-cholanate + glycine Thus, the two substrates of this enzyme are 3alpha,7alpha,12alpha-trihydroxy-5beta-cholan-24-oylglycine and H2O, whereas its two products are 3alpha,7alpha,12alpha-trihydroxy-5beta-cholanate and glycine. This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is 3alpha,7alpha,12alpha-trihydroxy-5beta-cholan-24-oylglycine amidohydrolase. Other names in common use include glycocholase, bile salt hydrolase, and choloyltaurine hydrolase. This enzyme participates in bile acid biosynthesis. Structural studies As of late 2007, 4 structures have been solved for this class of enzymes, with PDB accession codes , , , and . Research A 2018 study has linked the enzyme in gut bacteria to obesity and carbohydrate metabolism dominating over fat metabolism. References EC 3.5.1 Enzymes of known structure Obesity
