obsolete cyanidin 3-O-[2''-O-(xylosyl)-6''-O-(p-coumaroyl) glucoside] 5-O-glucosyltransferase activity (obsolete GO:0102584)
OBSOLETE. Catalysis of the reaction: cyanidin 3-O-[2''-O-xylosyl) 6''-O-(p-coumaroyl) glucoside + UDP-alpha-D-glucose = cyanidin 3-O-[2''-O-(xylosyl)-6''-O-(p-coumaroyl) glucoside] 5-O-glucoside + UDP + H+.
