Part:BBa_K2656107

GFP transcriptional unit 3

Transcriptional unit assembled with a one-pot [http://2018.igem.org/Team:Valencia_UPV/Design Level 1] Golden Gate reaction using BsaI type IIS endonuclease.

It is also a composite part of our [http://2018.igem.org/Team:Valencia_UPV/Part_Collection#com BioArt DNA toolkit palette: Printone ], as it can be used to express a green color with strong intensity.

This transcriptional unit is composed of the following standardized parts from our [http://2018.igem.org/Team:Valencia_UPV/Part_Collection Part Collection]:

• BBa_K2656007: the J23101 constitutive promoter in its Golden Braid compatible version
• BBa_K2656009: the J61100 strong ribosome biding site in its Golden Braid compatible version
• BBa_K2656022: the BBa_K2656022 GFPmut3b sequence in its Golden Braid standardized version
• Terminator BBa_K2656026: the B0015 transcriptional terminator in its Golden Braid compatible version

This transcriptional unit has been used to characterize the constitutive BBa_K2656007 promoter. Following this [http://2018.igem.org/Team:Valencia_UPV/Modeling#http://2018.igem.org/Team:Valencia_UPV/Experiments#exp_protocol experimental protocol], we have obtained the parameters to valide our [http://2018.igem.org/Team:Valencia_UPV/Modeling#models constitutive model] and so the results of the next graph have been obtained after an [http://2018.igem.org/Team:Valencia_UPV/Modeling#optimization optimization] and decision-making process, in which the optimal parameters have been selected and the constituent model for each objective has been simulated and compared with the experimental data.
