Sarsasapogenin 3β-glucosyltransferase


In enzymology, a sarsasapogenin 3β-glucosyltransferase is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are UDP-glucose and sarsasapogenin , whereas its two products are UDP and sarsasapogenin 3-O-β-D-glucoside.
The enzyme was first isolated from the root of the common asparagus. It is specific for substrate sterols with the uncommon 5β-configuration, that is with a cis-linkage between the A and B rings of the steroid nucleus.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:-spirostan-3-ol 3-O-β-D-glucosyltransferase. This enzyme is also called uridine diphosphoglucose-sarsasapogenin glucosyltransferase.
