Part:BBa_K3866007

Designed by: Venetios Michelioudakis   Group: iGEM21_Thessaly   (2021-09-23)


ParaBAD-pta-Terminator

Usage and Biology

This TU includes the Pta gene placed under the control of the arabinosed-induced promoter. The inducible promoter is used because cloning wasn't done. After the constitutive expression, the metabolism went out of balance so no colonies survied to be chosen for screening.

Design Notes

The coding sequence was domesticated . We removed BsmBI and BsaI sites in order to be compatible with GoldenBraid and MoClo. The sequence is cloned in p3 a1 vector and has overhangs compatible for GoldenBraid cloning.
