BBa_K215002 Is a BioBrick part that was made to work in conjunction with the Secretion System (BBa_K215107). When used it creates a fusion protein, that contains the prtB secretion signal recognized by the secretion system. It also fuses to the protein a nano-tag that is able to bind Streptavidin, TEV protease site (for isolating your protein from the fusion) and Histidine Epitote Tags for easy protein purification.
This part is composed of:

BBa_K215000

• Protein Expression Vector

BBa_K215001

• Fusion protein sequence

This part is used in: BBa_K215010

• GFP fusion protein

BBa_K215011

• BBa_K215090 (organic phosphotriesterase) fusion protein

BBa_K215091

Current Status: Complete

Future directions:

• Make more universal, to work with all proteins
• Optimize secretion-tag and nano-tag for fusion proteins

BBa_K215107 Is a BioBrick version of the Type 1 secretion system of Erwinia Chrysanthemi. It secretes proteins that contain the prtB C-terminus Epitote tag. To create a fusion protein with the prtB tag see BBa_K215002.

This part is composed of: BBa_K215100

• Gene encoding prtD

BBa_K215101

• Gene encoding prtE

BBa_K215102

• Gene encoding prtF

BBa_K215103

• BBa_K21500 + BBa_K21501 prtD + prtE

BBa_K215104

• BBa_K25103 + BBa_K25102 prtD + prtE + prtF

BBa_K215105

• BBa_K215104 + BBa_B0014 in PSB1AK3 prtDEF + Terminator

BBa_K215106

• BBa_K215104 + BBa_B0014 in PSB3T5 prtDEF + Terminator

BBa_K215108

• BBa_J23114 + BBa_K215106 Medium Promoter + prtDEF-Terminator

BBa_K215109

• BBa_J23113 + BBa_K215106 Weak Promoter + prtDEF-Terminator

Current Status: In progress

Future directions:

- Optimize RBS's

- Move secretion sequence into new plasmid, not TetR

- Try variety of cell lines.

BBa_K215200 is a Display vector that will allow for the presentation of any protein onto the surface of a cell by fusing the protein to Outer Membrane Protein A (OMPA). The fusion protein contains a GS peptide linker to space the displayed protein away from the outer membrane and also contains a TEV protease site to allow for purification of the displayed protein.

Current Status: In progress

Future Directions:

- Use new CDS display vector to display streptavidin

- Design monomeric protein to bind peptide sequence

- Utilize other proteins on CDS to test for activity of other proteins
