Target Vector

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

• Current Status: Complete

Secretion System

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

Display System

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.

• This Part is composed of:
  • BBa_K215201: Display Vector with 5 trans-membrane OMPA
  • BBa_K215250: Coding Sequence for fusion protein scaffold, 1 trans-membrane OMPA
  • BBa_K215251: Coding Sequence for fusion protein scaffold, 5 trans-membrane OMPA

• This Part is used in:
  • BBa_K215210: Display system (1 trans-membrane) in protein expression vector
  • BBa_K215211: Display system (5 trans-membrane) in protein expression vector
  • BBa_K215260: BBa_K215210 fused to Streptavidin
  • BBa_K215261: BBa_K215211 fused to Streptavidin

• Current Status: In progress
