pUPD2 for Golden Braid

Level 0 vector for Golden Braid assembly. The Level 0 modules are Interchangable parts in order everyone can use it as it is without any modification based on Golden Braid grammar.LacZa module as cargo for Blue White Screening between 2 BsmBI sites and 2 BtgzI sites. Resistance in Chloramphenicol and ori pMB1.

Usage and Biology

GoldenBraid (GB) is a DNA assembly strategy for Plant Synthetic Biology based on Type IIS enzymes. It is also compatible for MoClo assembly. The sequences must not contain BsmBI and BsaI sites! Domestication may be done in order to vanish BsaI and BsmBI sites from the inner sequence.

GB proposes an alternative view of modular cloning, and essentially the change is that you can infinitely build assemble new vectors by performing “braids”.[1] Using BsmBI another big advantage is the use of a single level 0 vector (pUPD and pUPD2, where pUPD2 is derived from iGEM-borne pSB1C3) for any GBpart one needs.

Then combining the desirable fragments from level 0; ‘level alpha’ (level a) cloning is succeeded creating Transcription Units (TU). Desirable TUs are combined to result in (Level Ω) cloning.

• Using BsmBI for Level 0 modules and ‘level omega’ (Level Ω)
• Using BsaI for ‘Level alpha’ (Level a)

But this is not the end, GoldenBraid outperforms GoldenGate (which everyone knows) because of the ability to continuously clone TUs in an “exponential” manner, compared to the linear progression GoldenGate. Bianry assembly of 2 Level Ω (Level 2 for MoClo) result in an alpha vector. Again Binary assembly of 2 alpha result in an omega vector. With this assembly you can insert step by step as many parts and as many TUs you want with high efficiency.
