ID 2.4.1.190 DE luteolin-7-O-glucuronide 2''-O-glucuronosyltransferase. AN LMT. AN uridine diphosphoglucuronate-luteolin 7-O-glucuronide AN glucuronosyltransferase. CA luteolin 7-O-beta-D-glucuronide + UDP-alpha-D-glucuronate = luteolin 7-O- CA [(beta-D-glucuronosyl)-(1->2)-(beta-D-glucuronide)] + UDP + H(+). 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). //
