Peptide production :
In the project by iGEM 13 Team TU Delft, a SUMO-peptide fusion was opted as a suitable expression system as they make the fusion proteins more soluble. The peptide by itself is not soluble in the cytoplasm but making a fusion of peptide with Small Ubiquitin like Modifiers (SUMO) will increase the solubility of the peptide, thus increasing the cytoplasmic fraction of the peptide.
A gene was constructed in such a way that the SUMO-peptide production was driven by the strong T7 phage promoter. This gene containing plasmid was harboured in a BL21(DE3) strain that has lac promoter driven T7 polymerase. Upon induction by IPTG the SUMO peptide fusion is produced as a soluble protein fraction.
The protocol can be seen [http://2013.igem.org/Team:TU-Delft/Protocol_10#protocol_10 here].
