Enzyme
Specific for the penultimate step in salvianin biosynthesis. The enzyme also catalyses the malonylation of shisonin to malonylshisonin [cyanidin 3-O-(6''-O-p-coumaryl-beta-D-glucoside)-5-(6'''-O-malonyl-beta-D-glucoside)]. The compounds 4'''-demalonylsalvianin, salvianin, pelargonidin 3,5-diglucoside and delphinidin 3,5-diglucoside cannot act as substrates.
