BioBricks: Genomic BRIDGEs
For the BRIDGE protocol we have one main BioBrick, which is the construct required for the two-step markerless insertion, a composite construct of cat (chloramphenicol resistance) and sacB (prevention of growth on sucrose).
In addition, we submitted the up- and downstream sequences of an example of a useful gene to be removed from the E. coli genome using the BRIDGE protocol: tnaA, which produces indole, such that when it is removed E. coli no longer smells!
| Name | Type | Link | Description |
|---|---|---|---|
| cat | Translational Unit | BBa_K322210 | Chloramphenicol acetyltransferase (chloramphenicol resistance gene). |
| sacB | Translational Unit | BBa_K322921 | Bacillus subtilis levansucrase, lethal to E. coli in the presence of sucrose. |
| cat-sacB construct | Composite | BBa_K322922 | Construct necessary for BRIDGE protocol. |
| tnaA upstream region | Other | BBa_K322705 | Upstream region of E. coli tryptophanase locus, used for targetting genes to this locus using BRIDGE. |
| tnaA downstream region | Other | BBa_K322706 | Downstream region of E. coli tryptophanase locus, used for targetting genes to this locus using BRIDGE. |
