Background
Today, the use of maggot therapy has become widespread due to the increase in chronic ulcers in the world. The recombinant production of secreted enzymes from these larvae is a novel non-invasive method for the treatment of chronic ulcers. Lucilia sericata (L. sericata) collagenase (MMP-1) has been expressed in insect cells. Collagenase is an enzyme that is widely used in clinical therapy and industry. It has been indicated that collagenase is expressed and secreted in salivary glands of L. sericata while using for maggot debridement therapy.Objectives
In the present study we decided to produce the recombinant form of collagenase enzyme in Spodoptera frugiperda (SF9) insect cells using the baculovirus expression system (Bac-to-Bac).Materials and Methods
cloned the coding sequences (residues 494-1705) of L. sericata collagenase into the pFastBacHTA as donor plasmid. After transposition in the bacmid of DH10Bac host, the bacmid was transfected into the Sf9 cell line, then the expressed recombinant collagenase (MMP-1) was purified using the Ni-NTA agarose.Results
The recombinant protein was verified by Western blotting. Furthermore, the biological activity of purified protein was measured in the presence of its specific substrate and its inhibitor, which was 67 IU.mL-1 based on our results, it was revealed that the characterized gene in our previous study codes L. sericata collagenesa enzyme.Conclusion
Considering to the broad applications of collagenase in medical sciences, for the first time, we cloned the L. sericata collagenase (MMP-1) gene into the insect cell line to establish a method for the expression and purification of L. sericata collagenase (MMP-1). The result help for preparing and designing a safe and versatile recombinant drug in future.Keywords:
