General annotation (Comments)

Function	Controls carbon flux to pigments essential for pollination or UV protection, to numerous pytoalexins synthesized by plants when challenged by pathogens, and to lignins. Ref.1
Catalytic activity	Trans-cinnamate + NADPH + O2 = 4-hydroxycinnamate + NADP+ + H2O.
Cofactor	Heme group By similarity.
Pathway	Phenylpropanoid metabolism; 4-coumaric acid biosynthesis; 4-coumaric acid from trans-cinnamic acid: step 1/1.
Developmental stage	Detectable 2 hours after elicitation and disappears after 6 hours. Ref.1
Induction	By elicitation. Ref.1
Sequence similarities	Belongs to the cytochrome P450 family.
