ENZYME entry: EC 2.3.1.172

Accepted Name
anthocyanin 5-O-glucoside 6'''-O-malonyltransferase.
Alternative Name(s)
Ss5MaT1.
Reaction catalysed
malonyl-CoA + pelargonidin 3-O-(6-O-[(E)-caffeoyl]-beta-D-glucoside) 5-O-beta-D-glucoside <=> 4'''-demalonylsalvianin + CoA
Comment(s)
  • Specific for the penultimate step in salvianin biosynthesis.
  • The enzyme also catalyzes 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.
