The fragment encoding aromatase (CYP19) with 45 N-terminal amino acids cut-off was cloned into pPIC9K vector and transformed to the yeast Pichia pastoris. The multi-copy recombinant strain was selected for the production of recombinant aromatase. The catalytic bioactivity of secreted enzyme was further verified by fluorescent substrate detection method. The results indicate that aromatase was successfully expressed in recombinant Pichia pastoris strain and secreted into the culture supernatant. The extracellular expression of the bioactive aromatase by P. pastoris provides us a better alternative for aromatase commercial production and promotes the research progress for the discovery of novel aromatase.
