T7_Promoter-RBS-TnaA-T7_Terminator

A part for TnaA expression in the preliminary experiment.


Biology

TnaA cleaves 6-Br-Trp into 6-Br-indole, pyruvate and ammonia, so we can use this composite part to synthetic 6-Br-indole as the second step to product 6,6’-dibromo indigo.


Usage

We construct the composite part BBa_K3332052 and transformed it into E.coli DH5α& E. coli BL21 (DE3) to verify its expression.


Characterization

1.Identification After plasmid construction, we performed PCR to certify and the resulting was shown down.

2.The proof of expression We used IPTG to induce the expression at different times.
