Vibrio natriegens' TorA signal peptide
This part contains Vibrio natriegens' TorA Tat signal peptide. It is a twin-arginine (RR) motif containing signal peptide for periplasmic transport of proteins via the twin-arginine translocation (Tat) pathway. Derived from Vibrio natriegens’ torA gene.
Biology
The twin-arginine translocation (Tat) pathway is capable of translocating fully folded proteins up to 150 kDa. It also contains a quality control feature of rejecting misfolded proteins. In some cases, disulfide bridge formation is not required for successful translocation. (Alanen et al., 2015)
Translocation using the tat-pathway requires the protein to contain a N-terminal signal peptide with a twin-arginine (RR) motif. The signal peptide is cleaved during the translocation process. A pair of V. natriegens’ native twin-arginine signal peptides identified by Aalto-Helsinki can be found here (TorAand Aminotransferase)
Use
This part can be N-terminally fused with your protein of choice to facilitate its periplasmic transport via the twin-arginine translocation (Tat) pathway.
Aalto-Helsinki 2019 used this part by combining it with YGFP, a slow-bleaching GFP variant, creating a composite TorA-YGFP part ([ ]) to test protein translocation into Vibrio natriegens' and Escherichia coli's periplasm.
