In [[Biology:Enzymology|enzymology]], a '''luteolin-7-O-glucuronide 2"-O-glucuronosyltransferase''' ({{EC number|2.4.1.190}}) is an [[Biology:Enzyme|enzyme]] that [[Chemistry:Catalysis|catalyzes]] the [[Chemistry:Chemical reaction|chemical reaction]]

:UDP-glucuronate + luteolin 7-O-beta-D-glucuronide <math>\rightleftharpoons</math> UDP + luteolin 7-O-[beta-D-glucuronosyl-(1→2)-beta-D-glucuronide]

Thus, the two [[Biology:Substrate (biochemistry)|substrates]] of this enzyme are UDP-glucuronate and luteolin 7-O-beta-D-glucuronide, whereas its two [[Chemistry:Product|products]] are [[Chemistry:Uridine diphosphate|UDP]] and luteolin 7-O-(beta-D-glucuronosyl-(1→2)-beta-D-glucuronide).

This enzyme belongs to the family of [[Biology:Glycosyltransferase|glycosyltransferase]]s, specifically the hexosyltransferases.  The [[Biology:List of enzymes|systematic name]] of this enzyme class is '''UDP-glucuronate:luteolin-7-O-beta-D-glucuronide 2<nowiki>''</nowiki>-O-glucuronosyltransferase'''. Other names in common use include '''uridine diphosphoglucuronate-luteolin 7-O-glucuronide''', '''glucuronosyltransferase''', '''LMT''', and '''UDP-glucuronate:luteolin 7-O-glucuronide-glucuronosyltransferase'''.
