SUMO tag :: Glycine-Serine Linker

This part is not compatible with BioBrick RFC10 assembly but is compatible with the iGEM Type IIS Part standard which is also accepted by iGEM.

Usage and Biology

SUMO tag is a small protein with around 12 kDa. When expressing desired protein in E. coli, most protein will be insoluble which cause aggregation or instability. One solution to this situation is the fusion of desired protein with different tags or proteins which can increase the solubility. This part is a SUMO tag with a Glycine-Serine (GS) linker added at the 3’ end. SUMO tag is important to keep the stability (Henley, J. M. et al., 2007) and increase the solubility (Kuo, D. et al., 2014) in both prokaryote and eukaryote. The GS linker will be used to fuse the SUMO with metallothionein (Li, X. et al., 2021) to increase the protein stability and solubility in E. coli. For JUMP assembly, this part is designed as a O part.
