In enzymology, a luteolin 7-O-glucuronosyltransferase () is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are UDP-glucuronate and luteolin, whereas its two products are UDP and luteolin 7-O-beta-D-glucuronide.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucuronate:luteolin 7-O-glucuronosyltransferase. Other names in common use include uridine diphosphoglucuronate-luteolin 7-O-glucuronosyltransferase, and LGT.
