DsbA+MBP(Pb)

the periplasm display protein Dsba-MBP, which binding the lead of the enviroment. Disulfide bond formation protein A (DsbA) is a powerful oxidative protein of the thioredoxin family. DsbA can help protein to fold correctly both in vivo and in vitro 。The C-terminal fusion protein of the maltose-binding protein can be efficiently and rapidly output into the periplasm as a key component of the expression of the metal-binding peptide of the cyclin.

Our sequence optimization is based on the sequence provided of Peking University's IGEM in 2010.(:BBa_K346004)The optimization of this sequence is more suitable for the expression of Bacillus megaterium.
