WebCitation 12 Cinnamate 4-hydroxylase (C4H) is one of the leading enzymes in phenylpropanoid pathway, which catalyzes the second step of the pathway in converting the trans-cinnamate to coumarate. C4H is the member of P450 protein family and catalyzes the monooxygenation of vast variety of substrates. WebDiacetyl treatment repressed gene expression and decreased the activities of PAL (phenylalanine ammonia-lyase), C4H (cinnamate-4-hydroxylase) and 4CL (4-coumarate-CoA ligase), which thus reduced the accumulation of individual and total phenolic compounds. Moreover, diacetyl enhanced the antioxidant ability and reduced ROS …
