System Parts

educatETH E.coli consists of 11 parts that can be synthesized independently (want to know how this is done in the lab? Then visit our In the Lab page!) Please note that four of them (4,5 and 8,9) form together two functional system units. They have been separated to ensure comparable part lengths and thus enable easier introduction into plasmids. All parts are listed in the following:

Single System Parts
1 TetR production [http://partsregistry.org/Part:BBa_I739001 BBa_I739001] constitutive subsystem
2 LacI production [http://partsregistry.org/Part:BBa_I739002 BBa_I739002] constitutive subsystem
3 LuxR production [http://partsregistry.org/Part:BBa_I739003 BBa_I739003] constitutive subsystem
4 1st half of P22 cII / EYFP production [http://partsregistry.org/Part:BBa_I739004 BBa_I739004] reporting subsystem
5 2nd half of P22 cII / EYFP production [http://partsregistry.org/Part:BBa_I739005 BBa_I739005] reporting subsystem

Many of the above mentioned parts contain double promoters. This promoter constructs contain two independent classes of operator sites and can therefore be regulated by two different types of molecules. Double promoters form the basis of the inducible toggle switch and hence the memory of our learning system. This concept could also help future projects in developing devices and systems that need extended regulation. In the following, we introduce a selection of first generation double promoters to the [http://partsregistry.org/Main_Page Registry of Standard Biological Parts]:

Double Promoters
1' cI negative / tetR negative promoter [http://partsregistry.org/Part:BBa_I739102 BBa_I739102] reporting subsystem
2' lacI negative / P22 cII negative promoter [http://partsregistry.org/Part:BBa_I739103 BBa_I739103] reporting subsystem
3' luxR/HSL positive / P22 cII negative promoter [http://partsregistry.org/Part:BBa_I739104 BBa_I739104] learning subsystem
4' luxR/HSL positive / cI negative promoter [http://partsregistry.org/Part:BBa_I739105 BBa_I739105] learning subsystem
5' tetR negative / P22 cII negative promoter [http://partsregistry.org/Part:BBa_I739106 BBa_I739106] reporting subsystem
6' cI negative / lacI negative promoter [http://partsregistry.org/Part:BBa_I739107 BBa_I739107] reporting subsystem


Proof of Concept
1" PoC promoter [http://partsregistry.org/Part:BBa_I739101 BBa_I739101] proof of concept, no part of the system
2" PoC intermediate [http://partsregistry.org/Part:BBa_I739014 BBa_I739014] proof of concept, no part of the system
3" PoC composite [http://partsregistry.org/Part:BBa_I739021 BBa_I739021] proof of concept, no part of the system


Plasmids
1"' pBR322BB1 [http://partsregistry.org/Part:BBa_I739201 BBa_I739201] high-copy cloning vector, ApR
2"' pCK01BB1 [http://partsregistry.org/Part:BBa_I739202 BBa_I739202] low-copy cloning vector, CmR
3"' pACYC177BB1 [http://partsregistry.org/Part:BBa_I739203 BBa_I739203] low-copy cloning vector, KmR
