obsolete cyanidin 3-O-[2''-O-(2''-O-(sinapoyl) xylosyl) 6''-O-(p-coumaroyl) glucoside] 5-O-[6''-O-(malonyl) glucoside] sinapoyltransferase activity (obsolete GO:0102586)
OBSOLETE. Catalysis of the reaction: cyanidin 3-O-[2''-O-(xylosyl)-6''-O-(p-coumaroyl) glucoside] 5-O-malonylglucoside + 1-O-sinapoyl-beta-D-glucose = cyanidin 3-O-[2''-O-(2''-O-(sinapoyl) xylosyl) 6'-O-(p-coumaroyl) glucoside] 5-O-[6''-O-(malonyl) glucoside + beta-D-glucose.
