Design Notes
- The virA gene is under the control a medium strong constitutive promoter so there is enough VirA receptor expressed but not too much so the cell suffers from the expression (VirA is a membrane protein)
- The virG gene is mutated so it works without an rpoA subunit from Agrobacterium tumefaciens ([http://www.springerlink.com/content/wmq06kua5qkma1au/ YC Jung et al., 2004])
- Double terminator (forward) to keep expression of mRFP by the constitutive promoter low.
- mRFP gene to show the activity of the vir promoter.
- This BioBrick is for measuring the natural VirA/G system.
Source
- virA from A. tumefaciens C58 (BBa_K389001)
- virG gene synthesized by Mr. Gene (BBa_K389002)
- vir promoter from A. tumefaciens C58 (BBa_K389003)
- Constitutive promoter, RBS, double terminator and mRFP from parts.igem (BBa_J23110, BBa_B0034, BBa_B0017, BBa_E1010)
