ID 2.3.1.302 DE hydroxycinnamoyl-CoA:5-hydroxyanthranilate N-hydroxycinnamoyltransferase. CA (1) (E)-4-coumaroyl-CoA + 5-hydroxyanthranilate = avenanthramide A + CoA. CA (2) (E)-caffeoyl-CoA + 5-hydroxyanthranilate = avenanthramide C + CoA. CC -!- The enzyme participates in the biosynthesis of avenanthramides, CC phenolic alkaloids found mainly in oats (Avena sativa). CC -!- It is related to EC 2.3.1.133. CC -!- The enzyme from oat does not accept feruloyl-CoA as a substrate. DR Q7XXP3, HHT1_AVESA ; A0A4Y5UJ70, HHT4_AVESA ; //
