obsolete caffeoyl-CoA:delphinidin-3,5-diglucoside 5-O-glucoside-6-O-hydroxycinnamoyltransferase activity (obsolete GO:0102815)
OBSOLETE. Catalysis of the reaction: delphinidin 3-O-beta-D-glucoside-5-O-beta-D-glucoside betaine + caffeoyl-CoA = delphinidin 3-O-glucosyl-5-O-caffeoylglucoside + coenzyme A.
