Native Eut Microcompartment with Surface His-tag display

Bacterial microcompartments (MCP)are natural existing nano-bioreacters inside some bacteria species. They are Protein-based polyhedral microcompartments which ranges from 20-200 nm in diameter. Despite its versality is side, their main function is enhance unfavoured metabolic reaction by sequestering functionally related enzymes, regulating substrate and small metabolites access. Eut microcompartment BBa_K311004 is one example which has been established by [http://2010.igem.org/Team:Minnesota/Project Team Minnesota 2010]

Different kinds of protein cage with various size have been engineered as target specific nano-containers: e.g.Viral capsids, ferritins & heat shock proteins. One important feature to enable the use of target-specific nano-container is the editable nature of protein cage's surface. We investigated the possibility to display specific peptide on the Eut microcompartment surface.

We find, among the 5 structural genes for the assembly of Eut MCP, EutS is suitable for surface peptide display.

EutS monomer N terminus is extruding out of the EutS hexamer’s surface.Studies showed that convex side of the EutS hexamer is the exterior side of Eut MCP.
