Parent Class:

EC-Numbers → 2 -- Transferases → 2.4 -- Glycosyltransferases → 2.4.1 -- Hexosyltransferases

Synonyms: UDP-glucose:anthocyanin 3′,5′-O-glucosyltransferase, UA3′5’GZ

Systematic Name: UDP-glucose:delphinidin 3-O-(6′′-O-malonyl)-β-D-glucoside 3′-O-glucosyltransferase

Unification Links: BRENDA:2.4.1.249, ENZYME:2.4.1.249, IUBMB-ExplorEnz:2.4.1.249

Reaction:
2 UDP-α-D-glucose + delphinidin 3-O-(6''-O-malonyl)-β-D-glucoside → ternatin C5 + 2 UDP + 2 H⁺

Summary:
Ternatins are a group of polyacetylated delphinidin glucosides that confer blue color to the petals of butterfly pea ( Clitoria ternatea). This enzyme catalyses two reactions in the biosynthesis of ternatin C5: the conversion of delphinidin 3-O-(6''-O-malonyl)-β-D-glucoside to delphinidin-3-O-(6''-O-malonyl)-β-glucoside-3'-O-β-glucosided, followed by the conversion of the later to ternatin C5, by transferring two glucosyl groups in a stepwise manner [Kogawa07].
