Baicalein 7-O-glucuronosyltransferase (, UBGAT) is an enzyme with systematic name UDP-D-glucuronate:5,6,7-trihydroxyflavone 7-O-glucuronosyltransferase . It catalyses the following chemical reaction
The enzyme characterised from Scutellaria baicalensis transfers a glucuronic acid sugar unit from UDP-glucuronate to the flavone, baicalein, specifically at the phenolic hydroxy group at the 7-position.
