SdyTag can achieve covalent binding of proteins through Tag-Catcher interaction.
SdyTag is a fibronectin-binding protein. It can cooperate with SdyCatcher to achieve covalent binding of proteins through Tag-Catcher interaction. SdyTag and SdyCatcher can also be used alongside SpyTag-SpyCatcher partners, to demonstrate kinetically controlled directed protein ligation, domain specific protein circularization and macromolecular assembly [1].
Usage and Biology
We devised the fusion expression of SdyTag with spNW15 and SnoopCatcher (namely SnCSdT). We employed SdyTag and SdyCatcher to link two proteins - SCSdC-mCh[1-10] and SnCSdT.
Characterization
We used SDS-PAGE to test whether the protein containing SdyTag had been expressed successfully(Figure 1). The molecular weight of SnCSdT (containing SdyTag) is 42.1 kDa. And we purified the target protein with a molecular weight of approximately 43 kD (Lane 5 - Lane 8), which demonstrated that we had successfully expressed the protein containing SdyTag.
Figure 1.SDS-PAGE analysis of the extraction results of SnCSdT (containing SdyTag).The gel was run at 80 V for 10 minutes and then at 150 V for 20 minutes, followed by staining with Coomassie Brilliant Blue. The molecular weight of SnCSdT-M15-GS is 42.1 kDa.
