EC 2.4.1.189     
Accepted name: luteolin 7-O-glucuronosyltransferase
Reaction: UDP-α-D-glucuronate + luteolin = UDP + luteolin 7-O-β-D-glucuronide
Other name(s): uridine diphosphoglucuronate-luteolin 7-O-glucuronosyltransferase; LGT; UDP-glucuronate:luteolin 7-O-glucuronosyltransferase
Systematic name: UDP-α-D-glucuronate:luteolin 7-O-glucuronosyltransferase (configuration-inverting)
Comments: The enzyme participates in the biosynthesis of luteolin triglucuronide, the major flavone found in the photosynthetically-active mesophyll of the primary leaves of Secale cereale (rye).
