Part:BBa_K3722007
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.
