Luteolin-7-O-glucuronide 2"-O-glucuronosyltransferase (EC 2.4.1.190) is an enzyme that catalyzes a chemical reaction which converts the flavone, luteolin-7-O-glucuronide, to a disaccharide by adding a sugar acid at one of the hydroxy groups of the starting material, which is the product of a similar reaction catalyzed by luteolin 7-O-glucuronosyltransferase, with uridine diphosphate (UDP) as byproduct. It was characterised from rye.[1][2]

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-glucuronide 2''-O-glucuronosyltransferase. Other names in common use include uridine diphosphoglucuronate-luteolin 7-O-glucuronide, glucuronosyltransferase, LMT, and UDP-glucuronate:luteolin 7-O-glucuronide-glucuronosyltransferase.[3]
