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.
