| Other name(s): |
uridine diphosphoglucuronate-luteolin 7-O-glucuronide glucuronosyltransferase; LMT; UDP-glucuronate:luteolin 7-O-glucuronide-glucuronosyltransferase; UDP-glucuronate:luteolin-7-O-β-D-glucuronide 2′′-O-glucuronosyltransferase |
| Systematic name: |
UDP-α-D-glucuronate:luteolin-7-O-β-D-glucuronide 2′′-O-glucuronosyltransferase (configuration-inverting) |
| Comments: |
The enzyme participates in the biosynthesis of luteolin triglucuronide, the major flavone found in the photosynthetically-active mesophyll of the primary leaves of Secale cereale (rye). |
