A degenerate set of PCR primers based on two conserved regions (heme binding region and oxygen ligand pocket) were designed and successfully applied to amplify DNA fragments of cytochrome P450 hydroxylase (CYP) genes from a rare actinomycetes, S. benihana. The PCR amplified products were employed as a DNA probe to clone the entire CYP genes from S. benihana genomic library. Five different CYP-positive cosmids were isolated by colony hybridization as well as PCR confirmation. The complete nucleotide sequencing of five different CYP genes revealed that each unique CYP showed a significant amino acid homology to previously-known CYP genes involved in streptomycetes secondary metabolism.
