Known Conditions

This table illustrate some basic information of pdu shell protein family.[http://www.ncbi.nlm.nih.gov/pubmed/20417607]

Table 1| Basic information of pdu shell protein family.

Figure 1| 3-dimension structure of the known shell proteins from Salmonella enterica . UPPER: pduU. [http://www.ncbi.nlm.nih.gov/pubmed/18786396] MIDDLE: pduA. [http://www.ncbi.nlm.nih.gov/pubmed/20870711] DOWN：pduT. [http://www.ncbi.nlm.nih.gov/pubmed/20870711 [3]]

Hypothesis

I）Pdu N is the vertex and its pentametic structures

for its identity with a proved vertex pentametic protein---CcmL. [http://www.ncbi.nlm.nih.gov/pubmed/18292340]

Figure 2| A diagram showing the construction of a large icosahedron from many smaller hexagons and 12 pentagons at the vertices. The figure shown has a triangulation number (T) of 75 (29). [http://www.ncbi.nlm.nih.gov/pubmed/18292340 [4]]

II) Hexamers forms the facets, which comprises the building blocks of bacterial microcompartment shells
