Constitutive expression of sfGFP with OmpA secretion tag
sfGFP BBa_K4244004 was fused to OmpA BBa_K208003 to secrete sfGFP and use it as an extracellular reporter. It is under an constitutive medium strength promoter BBa_K4244057.
Secretion assay
Discussion
No secretion was observed in E. coli Nissle. This may be due to the too high expression level of sfGFP under BBa_K4244057. This experiment still need adjustment and fine tuning to prove the secretion of sfGFP.
