Reaction: caffeoyl-CoA + putrescine = CoA + N-caffeoylputrescine
Other name(s): caffeoyl-CoA putrescine N-caffeoyl transferase; PHT; putrescine hydroxycinnamoyl transferase; hydroxycinnamoyl-CoA:putrescine hydroxycinnamoyltransferase; putrescine hydroxycinnamoyltransferase
Systematic name: caffeoyl-CoA:putrescine N-(3,4-dihydroxycinnamoyl)transferase
Comments: Feruloyl-CoA, cinnamoyl-CoA and sinapoyl-CoA can also act as donors, but more slowly.
