Linking MaFMO and TnaA together can achieve the simultaneous expression of two enzymes in one cell, greatly improving the efficiency of the reaction.
Biology
This part can achieve the highest yield of producing and simply the reaction process. Only one kind of engineering bacteria can product 6,6’-dibromo indigo.
Usage
We ligased TnaA (BBa_K3722000) and MaFMO (BBa_K3722002) on the expression vector pET-28a(+) to get this composite part by In-Fusion. Then we transformed it into E. coli DH5α & E. coli BL21(DE3).
Characterization
1.The verification of the expression
- Fig.1 SDS-PAGE analysis of MaFMO .Induction condition: LB media, OD600 0.6 ~ 0.8, IPTG 0.1 mM, 18°C and 200 rpm.(1:negitive control 2: 3.5h 3:9h 4:10h 5:11h 6:12h)
2.Productive result Excellent production effect was obtained after adding 6-Br-Trp. We compared two reaction systems by Microplate Reader, and found BBa_K3722011 was more productive. We suspected that this is due to the transmenmbrane transport of 6-Br-indole was skipped.
- Fig.2 The absorption curves of Tyrian Purple production.
