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 (YC Jung et al., 2004)
- double terminator (forward) to keep expression of luciferase gene by the constitutive promoter low
- luciferase gene to show the activity of the vir promoter
- this BioBrick is for measuring the behaviour of 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)
- luciferase gene from Promega's pGL4.10luc2 vector (BBa_K389004)
- constitutive promoter, RBS and double terminator from parts.igem (BBa_J23110, BBa_B0034, BBa_B0017)
