DE   luteolin-7-O-diglucuronide 4'-O-glucuronosyltransferase.
CA   luteolin 7-O-[(beta-D-glucuronosyl)-(1->2)-(beta-D-glucuronide)] + UDP-
CA   alpha-D-glucuronate = H(+) + luteolin 7-O-[(beta-D-glucuronosyl)-(1->2)-
CA   (beta-D-glucuronide)] 4'-O-beta-D-glucuronide + UDP.
CC   -!- The enzyme participates in the biosynthesis of luteolin
CC       triglucuronide, the major flavone found in the photosynthetically-
CC       active mesophyll of the primary leaves of Secale cereale (rye).
