摘要: The enzyme cinnamate 4-hydroxylase (C4H, EC 1.14.13.11), which belongs to the cytochrome P450 family, is involved in the phenylpropanoid pathway. Using RACE, full-length cDNA consisting of 2063 nucleotides encoding C4H (designated DfC4H) was isolated from Dryopteris fragrans (L.) Schott. A number of 1527 of nucleotides composed the complete open reading frame (ORF) of the cDNA (GenBank Accession Number KF830705.2). A protein that consisted of 508 amino acids with a calculated molecular mass of 58.1908 kDa was predicted to be encoded by this ORF. The overexpression of DfC4H was observed to increase significantly p-coumaric acid and anthocyanin levels in transgenic Arabidopsis thaliana.
