Reaction: 2 sinapoyl-CoA + spermidine = 2 CoA + N1,N8-bis(sinapoyl)-spermidine
Other name(s): SDT
Systematic name: sinapoyl-CoA:spermidine N-(hydroxycinnamoyl)transferase
Comments: The enzyme from the plant Arabidopsis thaliana has no activity with 4-coumaroyl-CoA (cf. EC 18.104.22.168, spermidine dicoumaroyl transferase).
