Trx-His-EK tagged subtilisin-like protease
Subtilisin-like protease is a kind of alcalase found in amphioxus (Branchiostoma) similar to subtilisin protease. In our project, it has been used to degrade microcystin with another enzyme called carboxypeptidase Z/N.
Microcystin RR Degradation Efficiency
Similar to subtilisin, our subtilisin-like protease can catalyze the hydrolysis of protein to amino acid. Subtilisin has been widely used in all walks of life even in laundry.
Interestingly, we found the subtilisin-like protease can degrade not only proteins but also microcystins. Then we test the activity of this enzyme and measured by HPLC-MS-MS.
The results shows that subtilisin-like protease cannot degrade MC-RR effectively alone, but when mixed with carboxypeptidase Z/N, it can strongly degrade MC-RR. In our project, we cloned this part into pET32a vector and transformed it into E.coli(DH5α) for mass production of subtilisin-like protease .
