Fusion part of pBAD arabinose-inducible induction system and the HRV 14_3C protease
This BioBrick is a 2 part fusion of arabinose-inducible induction system and the HRV 14_3C protease. The recombinant type 14_3C protease from human rhinovirus (HRV 3C) recognizes the same cleavage site as the native enzyme: LeuGluValLeuPheGln↓GlyPro.
The small, 22 kDa size of the protease got its optimal activity at 4°C but is still very active at 37°C. It is commonly used for an easy tag removal after the purification of recombinant proteins carrying his-tag. The 14_3C works with a catalytic triade, containing the amino acid residues Ser-Asp-His at its active site.
The arabinose-inducible induction system was amplified via PCR from the pBAD_iGEMexpress vector and fused via NgoMIV with the HRV 14_3C protease. An effective induction can be accomplished with 2 mM up to 25 mM arabinose.
