Streptomyces griseus is a species of bacteria in the genus Streptomyces commonly found in soil. A few strains have been also reported from deep-sea sediments. It is a Gram-positive bacterium with high GC content. Along with most other streptomycetes, S. griseus strains are well known producers of antibiotics and other such commercially significant secondary metabolites. These strains are known to be producers of 32 different structural types of bioactive compounds. Streptomycin, the first antibiotic ever reported from a bacterium, comes from strains of S. griseus. Recently, the whole genome sequence of one of its strains had been completed.

The invention discloses a cytochrome P450 enzyme, a construction for electron transfer system engineering bacteria thereof and an application thereof and belongs to the technical field of biotechnology. The bacterial strain is the engineering strain which utilizes streptomyces griseus (ATCC13273) endogenous ferredoxin and ferredoxin reductase as P450 enzyme CYP105D1 electron transfer systems. The bacterial strain can be utilized to realize the specific oxygen-site demethylation for L-tetrahydropalmatine and supply the feasibility for utilizing genetic engineering strain biotransformation to produce L-corydalmine. Meanwhile, ferredoxin reductases capable of supporting CYP105D1 biological catalysis disclosed by the invention all can promote the biotransformation capacity of CYP105D1 for various natural products, can remove L-tetrahydropalmatine and can realize efficient conversion of natural products, such as, warfarin and 7-ethyoxyl coumarin. An embodiment is provided for efficient biotransformation based on P450.
