Function
function
Catalyzes the first oxidative step of the phenylpropanoid pathway in higher plants by transforming trans-cinnamate into p-coumarate (By similarity).
The compounds formed by this pathway are essential components for lignification, pollination, and defense against ultraviolet light, predators and pathogens

Catalytic activity
- (E)-cinnamate + O2 + reduced [NADPH--hemoprotein reductase] = (E)-4-coumarate + H+ + H2O + oxidized [NADPH--hemoprotein reductase]
Cofactor
Pathway
