In enzymology, a luteolin-7-O-diglucuronide 4'-O-glucuronosyltransferase ({{EC number|2.4.1.191}}) is an enzyme that catalyzes the chemical reaction

UDP-glucuronate + luteolin 7-O-beta-D-diglucuronide UDP + luteolin 7-O-[beta-D-glucuronosyl-(1->2)-beta-D-glucuronide]-4'-O-beta-D- glucuronide

Thus, the two substrates of this enzyme are UDP-glucuronate and luteolin 7-O-beta-D-diglucuronide, whereas its 4 products are UDP, luteolin, 2)-beta-D-glucuronide]-4'-O-beta-D-">7-O-[beta-D-glucuronosyl-(1->2)-beta-D-glucuronide]-4'-O-beta-D-, and 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-beta-D-diglucuronide 4'-O-glucuronosyltransferase. Other names in common use include uridine diphosphoglucuronate-luteolin 7-O-diglucuronide, glucuronosyltransferase, UDP-glucuronate:luteolin 7-O-diglucuronide-glucuronosyltransferase, UDPglucuronate:luteolin, 7-O-diglucuronide-4'-O-glucuronosyl-transferase, and LDT.
