SPYtag inserted Tm Encapsulin

Usage and Biology

TmEncapsulin is a protein found from Thermotoga maritima. A paper (Structural basis of enzyme encapsulation into a bacterial nano compartment) says that it consists of 60 monomers and forms capsule, Virus-like particle(VLP). iGEM also treats it as a useful part (BBa_K192000).

We used TmEncapsulin as a biological polymer. We put Spytag inside TmEncapsulin because we used SpyTag/SpyCatcher system to bind it to other parts. Also, this has three tag and cleavage sites. First is 6×His-tag inserted in the N-terminus of TmEncapsulin for protein purification. Second is HA-tag inserted between TmEncapsulin and 6x-His-tag to detect it by using antibodies. Third is a 6x-His tag because, in the paper, it was used for improving the heat-resistant ability of TmEncapsulin. (Programmable polyproteins built using twin peptide superglues) 

We put it between the BamHI site and the Ndel site on pET11-a. We used BL21 (DE3) for gene expression. We used the Ni-NTA Agarose for purification. After that, we confirmed the molecular weight of SpyCatcher inserted TmEncapusulin by using SDS-PAGE.
