It is a new method of producing high purity and non-pollution active peptide, to produce active proteins using oleosin expression system. In order to provide a basis for later development and utilization of oleosin expression system in Camellia oleifera, the specific primers were designed respectively taking oleosin gene and metallothionein gene in C. oleifera as templates. The CDS fragments were obtained by PCR amplification. The target DNAs were transformed into Escherichia coli BL21 （DE3） after the pET30a recombinant plasmid was constructe...
