In enzymology, a luteolin-7-O-glucuronide 2"-O-glucuronosyltransferase (EC 2.4.1.190) is an enzyme that catalyzes the chemical reaction

UDP-glucuronate + luteolin 7-O-beta-D-glucuronide UDP + luteolin 7-O-[beta-D-glucuronosyl-(1→2)-beta-D-glucuronide]

Thus, the two substrates of this enzyme are UDP-glucuronate and luteolin 7-O-beta-D-glucuronide, whereas its two products are UDP and luteolin 7-O-(beta-D-glucuronosyl-(1→2)-beta-D-glucuronide).

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.

Estradiol 3-glucuronide (E2-3G), also known as 17β-estradiol 3-(β-D-glucuronide), is a naturally occurring and endogenous estrogen conjugate. It is specifically the C3 glucuronide conjugate of estradiol, the major estrogen in the body. It is formed from estradiol in the liver by UDP-glucuronosyltransferase via attachment of glucuronic acid and is eventually excreted in urine and bile. Similarly to estrogen sulfates like estrone sulfate, estrogen glucuronides have much higher water solubility than do unconjugated estrogens like estradiol.
