Luteolin-7-O-glucuronide 2"-O-glucuronosyltransferase () 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.
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.
