Cinnamate-4-hydroxylase c4h
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.
